If set, implicit search is enabled

Check what the phase achieves, to be called at any point after it is finished.

A name given to the Phase that can be used to debug the compiler. For instance, it is possible to print trees after a given phase using:

$ ./bin/scalac -Xprint:<phaseNameHere> sourceFile.scala

List of names of phases that should precede this phase

Can this transform change the base types of a type?

Can this transform create or delete non-private members?

Can this transform change the parents of a class?

The sequence position of this phase in the given context where 0 is reserved for NoPhase and the first real phase is at position 1. -1 if the phase is not installed in the context.

Output should be checkable by TreeChecker

Is this phase the standard typerphase? True for TyperPhase, but not for other first phases (such as FromTasty or Parser). The predicate is tested in some places that perform checks and corrections. It's different from ctx.isAfterTyper (and cheaper to test).

If set, allow missing or superfluous arguments in applications and type applications.

Convert a compilation unit's tree to a string; can be overridden

Returns a string representation of the object.

The default representation is platform dependent.

The phase in which the transformation should be run. By default this is the phase given by the this macro transformer, but it could be overridden to be the phase following that one.
