    Here is where we:

    1) Read some source code, and put it in the "read" object. 2) Evaluate the read object, and put the result in the "eval" object. 3) Create a String for human consumption, and put it in the "print" object.

    Read! Eval! Print! Some of that not yet centralized here.

  5. case class ComputedImports(header: String, prepend: String, append: String, access: String) extends Product with Serializable

    Compute imports that allow definitions from previous requests to be visible in a new request.

    Compute imports that allow definitions from previous requests to be visible in a new request. Returns three or four pieces of related code:

    0. Header code fragment that should go at the beginning of the compilation unit, specifically, import Predef.

    1. An initial code fragment that should go before the code of the new request.

    2. A code fragment that should go after the code of the new request.

    3. An access path which can be traversed to access any bindings inside code wrapped by #1 and #2 .

    The argument is a set of Names that need to be imported.

    Limitations: This method is not as precise as it could be. (1) It does not process wildcard imports to see what exactly they import. (2) If it imports any names from a request, it imports all of them, which is not really necessary. (3) It imports multiple same-named implicits, but only the last one imported is actually usable.

    Bind a specified name to a specified value. The name may later be used by expressions passed to interpret.

    A fresh ReadEvalPrint, which defines a line package, is used to compile a custom eval object that wraps the bound value.

    If the bound value is successfully installed, then bind the name by interpreting val name = $line42.$eval.value.

    the variable name to bind

    It's a bit of a shotgun approach, but for now we will gain in robustness. Try a symbol-producing operation at phase typer, and if that is NoSymbol, try again at phase flatten.
