test performance please |
We only need to fully define the bounds of the PolyType parameters, not the whole PolyType.

There was a problem hiding this comment.
I have the impression it would be easier to just scan the type parameter bounds whether a fullyDefinedType is needed and, if yes, instantiate the whole type.
