Checker

If set, implicit search is enabled

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?

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

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.
