This sounds like a good idea. Many people, including myself, do find
elisp's REs a bit painful and its noticed even more these days since
perl compatible REs seem to have become a bit of a default standard. 

A modified read syntax certainly seems to be feasible and to my mind it
fits with a lisp way of doing things. Will be interesting to see how
easily that can be worked into emacs in a consistent way.
