    The values for the subpatterns, as computed by the extractor call in extractor, are stored in local variables that re-use the symbols in subPatBinders. This makes extractor patterns more debuggable (scala/bug#5739).

    An optimized version of ExtractorTreeMaker for Products.

    An optimized version of ExtractorTreeMaker for Products. For now, this is hard-coded to case classes, and we simply extract the case class fields.

    The values for the subpatterns, as specified by the case class fields at the time of extraction, are stored in local variables that re-use the symbols in subPatBinders. This makes extractor patterns more debuggable (scala/bug#5739) as well as avoiding mutation after the pattern has been matched (scala/bug#5158, scala/bug#6070)

    TODO: make this user-definable as follows When a companion object defines a method def unapply_1(x: T): U_1, but no def unapply or def unapplySeq, the extractor is considered to match any non-null value of type T the pattern is expected to have as many sub-patterns as there are def unapply_I(x: T): U_I methods, and the type of the I'th sub-pattern is U_I. The same exception for Seq patterns applies: if the last extractor is of type Seq[U_N], the pattern must have at least N arguments (exactly N if the last argument is annotated with : _*). The arguments starting at N (and beyond) are taken from the sequence returned by apply_N, and it is checked that that sequence has enough elements to provide values for all expected sub-patterns.

    For a case class C, the implementation is assumed to be def unapply_I(x: C) = x._I, and the extractor call is inlined under that assumption.

    implements the run-time aspects of (§8.2) (typedPattern has already done the necessary type transformations)

    Type patterns consist of types, type variables, and wildcards. A type pattern T is of one of the following forms:

    • A reference to a class C, p.C, or T#C. This type pattern matches any non-null instance of the given class. Note that the prefix of the class, if it is given, is relevant for determining class instances. For instance, the pattern p.C matches only instances of classes C which were created with the path p as prefix. The bottom types scala.Nothing and scala.Null cannot be used as type patterns, because they would match nothing in any case.
    • A singleton type p.type. This type pattern matches only the value denoted by the path p (that is, a pattern match involved a comparison of the matched value with p using method eq in class AnyRef). // TODO: the actual pattern matcher uses ==, so that's what I'm using for now // https://github.com/scala/bug/issues/4577 "pattern matcher, still disappointing us at equality time"
    • A compound type pattern T1 with ... with Tn where each Ti is a type pat- tern. This type pattern matches all values that are matched by each of the type patterns Ti.
    • A parameterized type pattern T[a1,...,an], where the ai are type variable patterns or wildcards _. This type pattern matches all values which match T for some arbitrary instantiation of the type variables and wildcards. The bounds or alias type of these type variable are determined as described in (§8.3).
    • A parameterized type pattern scala.Array[T1], where T1 is a type pattern. // TODO This type pattern matches any non-null instance of type scala.Array[U1], where U1 is a type matched by T1.

    The models we get from the DPLL solver need to be mapped back to counter examples.

    The models we get from the DPLL solver need to be mapped back to counter examples. However there's no precalculated mapping model -> counter example. Even worse, not every valid model corresponds to a valid counter example. The reason is that restricting the valid models further would for example require a quadratic number of additional clauses. So to keep the optimistic case fast (i.e., all cases are covered in a pattern match), the infeasible counter examples are filtered later.

    The DPLL procedure keeps the literals that do not contribute to the solution unassigned, e.g., for (a \/ b) only {a = true} or {b = true} is required and the other variable can have any value.

    This function does a smart expansion of the model and avoids models that have conflicting mappings.

    For example for in case of the given set of symbols (taken from t7020.scala): "V2=2#16" "V2=6#19" "V2=5#18" "V2=4#17" "V2=7#20"

    One possibility would be to group the symbols by domain but this would only work for equality tests and would not be compatible with type tests. Another observation leads to a much simpler algorithm: Only one of these symbols can be set to true, since V2 can at most be equal to one of {2,6,5,4,7}.
