I completely agree with John. Not having this rule is not just a
performance problem, it also leaks into the user model. For example:
- If you have a lazy collection, you can still call the eager `map` if
you provide matching type context.
- If a protocol extension method that was intended to be a default
implementation does not get selected as the implementation, then both
are visible on the type. This causes ambiguities when chaining.
