  An interface to enable higher configurability of diagnostic messages regarding type errors.

  An interface to enable higher configurability of diagnostic messages regarding type errors. This is barely a beginning as error messages are distributed far and wide across the codebase. The plan is to partition error messages into some broad groups and provide some mechanism for being more or less verbose on a selective basis. Possible groups include such examples as

  arity errors kind errors variance errors ambiguity errors volatility/stability errors implementation restrictions

  And more, and there is plenty of overlap, so it'll be a process.

### Deprecated Value Members

1.  def formatted(fmtstr: String): String
   Implicit
     This member is added by an implicit conversion from (TypeDiagnostics.this)#TypeDiag toStringFormat[(TypeDiagnostics.this)#TypeDiag] performed by method StringFormat in scala.Predef.
   Definition Classes
     StringFormat
   Annotations
     @deprecated @inline()
   Deprecated

     (Since version 2.12.16) Use `formatString.format(value)` instead of `value.formatted(formatString)`, or use the `f""` string interpolator. In Java 15 and later, `formatted` resolves to the new method in String which has reversed parameters.

2.  def →[B](y: B): ((TypeDiagnostics.this)#TypeDiag, B)
   Implicit
     This member is added by an implicit conversion from (TypeDiagnostics.this)#TypeDiag toArrowAssoc[(TypeDiagnostics.this)#TypeDiag] performed by method ArrowAssoc in scala.Predef.
   Definition Classes
     ArrowAssoc
   Annotations
     @deprecated
   Deprecated

     (Since version 2.13.0) Use `->` instead. If you still wish to display it as one character, consider using a font with programming ligatures such as Fira Code.
