abstractOverClass the type parameters and enclosing class parameters of originalDef,this of the enclosing class,originalDef.
Given an instance method definition originalDef, return a
fully parameterized method definition derived from originalDef, which
has derived as symbol and fullyParameterizedType(originalDef.symbol.info)
as info.
Given an instance method definition originalDef, return a
fully parameterized method definition derived from originalDef, which
has derived as symbol and fullyParameterizedType(originalDef.symbol.info)
as info.
abstractOverClass defines weather the DefDef should abstract over type parameters
of class that contained original defDef
Converts the type info of a member of class clazz to a method type that
takes the this of the class and any type parameters of the class
as additional parameters.
Converts the type info of a member of class clazz to a method type that
takes the this of the class and any type parameters of the class
as additional parameters. Example:
class Foo[+A <: AnyRef](val xs: List[A]) extends AnyVal { def baz[B >: A](x: B): List[B] = ... }
leads to:
object Foo { def extension$baz[B >: A <: Any, A >: Nothing <: AnyRef]($this: Foo[A])(x: B): List[B] }
If a self type is present, $this has this self type as its type.
if true, include the type parameters of the class in the method's list of type parameters.
if true, require created $this to be $this: (Foo[A] & Foo,this). This is needed if created member stays inside scope of Foo(as in tailrec)
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.

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

otherwise NoSymbol.

If references to some original symbol from given tree node within fully parameterized method
derived should be rewired to some fully parameterized method, the rewiring target symbol,
otherwise NoSymbol. By default implemented as
rewiredTarget(tree.symbol, derived)
but can be overridden.

Perform Step 1 in the inline classes SIP: Creates extension methods for all methods in a value class, except parameter or super accessors, or constructors.
Additionally, for a value class V, let U be the underlying type after erasure. We add to the companion module of V two cast methods: def u2evt$(x0: U): ErasedValueType(V, U) def evt2u$(x0: ErasedValueType(V, U)): U The casts are used in Erasure to make it typecheck, they are then removed in ElimErasedValueType. This is different from the implementation of value classes in Scala 2 (see SIP-15) which uses
asInstanceOfwhich does not typecheck.Finally, if the constructor of a value class is private pr protected it is widened to public.
