Check well-kindedness of type application (assumes arities are already checked) -- @M
This check is also performed when abstract type members become concrete (aka a "type alias") -- then tparams.length==1 (checked one type member at a time -- in that case, prefix is the name of the type alias)
Type application is just like value application: it's "contravariant" in the sense that the type parameters of the supplied type arguments must conform to the type parameters of the required type parameters:
e.g. class Iterable[t, m[+x <: t]] --> the application Iterable[Int, List] is okay, since List's type parameter is also covariant and its bounds are weaker than <: Int

A creator for existential types. This generates:
tpe1 where { tparams }
where tpe1' is the result of extrapolating tpe' wrt to tparams'. Extrapolating means

The raw to existential map converts a raw type to an existential type.
It is necessary because we might have read a raw type of a
parameterized Java class from a class file. At the time we read the type
the corresponding class file might still not be read, so we do not
know what the type parameters of the type are. Therefore
the conversion of raw types to existential types might not have taken place
in ClassFileparser.sigToType (where it is usually done)

Does type tp' implement symbol sym' with same or
stronger type? Exact only if sym' is a member of some
refinement type, otherwise we might return false negatives.

TODO: type params of anonymous type functions, which currently can only arise from normalising type aliases, are owned by the type alias of which they are the eta-expansion higher-order subtyping expects eta-expansion of type constructors that arise from a class; here, the type params are owned by that class, but is that the right thing to do?

A map to convert every occurrence of a type variable to a wildcard type
A merker object for a base type sequence that's no yet computed.
A merker object for a base type sequence that's no yet computed. used to catch inheritance cycles
A log of type variable with their original constraints.
A map of all loaded files to the rich compilation units that correspond to them.
The list of use cases of doc comment of symbol sym seen as a member of class
site.
The list of use cases of doc comment of symbol sym seen as a member of class
site. Each use case consists of a synthetic symbol (which is entered nowhere else),
of an expanded doc comment string, and of its position.
The symbol for which use cases are returned
The class for which doc comments are generated
when more than 10 successive expansions of the same string are done, which is interpreted as a recursive variable definition.
A map that associates with each abstract file the set of responses that are waiting (via waitLoadedTyped) for the unit associated with the abstract file to be loaded and completely typechecked.

A position that wraps a non-empty set of trees.
A position that wraps a non-empty set of trees. The point of the wrapping position is the point of the first trees' position. If some of the trees are ranges, returns a range position enclosing all ranges Otherwise returns first tree's position.
A position that wraps a set of trees.
A position that wraps a set of trees. The point of the wrapping position is the point of the default position. If some of the trees are ranges, returns a range position enclosing all ranges Otherwise returns default position.
