Analyzing Regular Expressions (Regexps)

[Nordlöw]

Does anyone know of code that analyzes the logical structure of native
emacs regular expressions (regexps). My primary wishes are to
1. check whether it contains any regexp special characters at all
2. determine the size limits (if any) of a given regexp

Maybe we could hook into the native C-code written logic for parsing
them and get this functionaliy.

Many thanks in advance,
Nordlöw
