I'll assume your don't really want to extend the language/compiler to
support those new type specifiers and only want them *in your modules*. :)
With that in mind, parse_transform looks like the tool for the job!
Using it you could specify those new fancy types and have them turned into
the [existing] 'binary' type on compilation
(more experience folks, what do ya think?).
To figure out how parse_transform works follow the first posts from this
