A name filter selects or discards a member name of a type pre.
To enable efficient caching, name filters have to satisfy the
following invariant: If keep is a name filter, and pre has
class C as a base class, then
keep(pre, name) implies keep(C.this, name)

An extractor for single abstract method types. A type is a SAM type if it is a reference to a class or trait, which
- has a single abstract method with a method type (ExprType and PolyType not allowed!)
- can be instantiated without arguments or with just () as argument.

An extractor for single abstract method types. A type is a SAM type if it is a reference to a class or trait, which
- has a single abstract method with a method type (ExprType and PolyType not allowed!)
- can be instantiated without arguments or with just () as argument.
The pattern SAMType(denot) matches a SAM type, where denot is the
denotation of the single abstract method as a member of the type.

In a TypeApply tree, a TypeVar is created for each argument type to be inferred. Every type variable is referred to by exactly one inferred type parameter of some TypeApply tree.
A type variable is essentially a switch that models some part of a substitution.
It is first linked to origin, a poly param that's in the current constraint set.
It can then be (once) instantiated to some other type. The instantiation is
recorded in the type variable itself, or else, if the current type state
is different from the variable's creation state (meaning unrolls are possible)
in the current typer state.
