I'm not completely sure why you would want this, but here's something
that I made before that might give you inspiration:
https://stackoverflow.com/questions/7657130/how-to-get-the-ast-of-a-regular-expression-string/21419351#21419351

Also, are you aware of Boost Xpressive? It's only tangentially
related, but in its core it has "static regexes" which are really
Spirit-style template expressions. The linking element here could be
that you can make the group matches trigger semantic actions just like
in spirit, which already tells you what part of the regular expression is involved.

Cheer,
