I tend to doubt it would help clean up the implementation of Phoenix
environments. These features exist on different meta-levels: one
(proto::let) is a feature for compiler-construction (Proto), the other
(phoenix::let) is a language feature (Phoenix). The have roughly the
same purpose within their purview, but as their purviews are separated
by one great, big Meta, it's not clear that they have anything to do
with each other.
