Is this only type-checking stuff, or does it impact
code-generation? Namely, does this build a new closure for
(f ~a:2.0) and then apply it to 2.0 and 4.0, or does it
recognize that this is a direct invocation of f, thus
skipping the closure creation?
This might be a relevant issue for inner loops, so I thought
I might ask.
