Why not? It seems like that would solve a lot of use-cases. People get
bringing up various new uses for prefix or suffix syntax that they want
built directly into the language. Providing a generic way to implement
third-party prefixes or suffixes would save having to put all of these
directly into the language. And it opens up a lot of other potential
use-cases as well.
