Just saw this, addressing the question:

"The current definition of concepts and requirements for use drowns the
programmer in complexities of a magnitude not warranted by the need to
express type-checked 9constrained) generic programming."

From: Simplifying the use of concepts, linked in the article.

- recursive instantiations of pure generics?
- an optional Compiler package?
