We could transform syntax from Elisp like to pcre using string substitution
on the fly. For the features not present in pcre just use different
set of functions,
regexp is self contained it is just a string.
Compiling regexp to a native code using gcc or GNU lightning (or any
other framework),
could also be a solution.
