[Ur] Regular expressions DSEL?

[Artyom Shalkhakov]

Hello all,

'm doing form validation stuff, following examples on MDN. [1]

It seems like Ur/Web doesn't handle regular expressions?

I guess it should not be too diffcult to define a DSEL in Ur/Web (just AST
constructors and a few trusted functions: e.g. [compile : AST -> regexp],
where [regexp] is an abstract type, or maybe just a string :-)) and have it
work at least in the browser.

Could somebody point me in the right direction here?
