import semmle.code.csharp.Unification

subsumes	Holds if type `t1` subsumes type `t2`. That is, it is possible to replace all type parameters in `t1` with some (other) types to make the two types equal.
unifiable	Holds if types `t1` and `t2` are unifiable. That is, it is possible to replace all type parameters in `t1` and `t2` with some (other) types to make the two substituted terms equal.

ConstrainedTypeParameter	A type parameter that is constrained.
UnconstrainedTypeParameter	A type parameter that is compatible with any type.
