AsSeenFromMap

Derived selection.

Expand parameter reference corresponding to prefix pre; If the expansion is a wildcard parameter reference, convert its underlying bounds to a range, otherwise return the expansion.

Whether it is currently expanding bounds

It is used to avoid following LazyRef in F-Bounds

Can the prefix of this static reference be omitted if the reference itself can be omitted? Overridden in TypeOps#avoid.

Can be overridden. By default, only the prefix is mapped.

Map this function over given type

Try to widen a named type to its info relative to given prefix pre, where possible. The possible cases are listed inline in the code.

Set to true when the result of apply was approximated to avoid an unstable prefix.
