pregexp: pregexp-propose-optimizations, pregexp-optimize, or similar?

Are there any functions available on the web that propose (or even do)
optimizations for a given pregexp expression (more specifically,
for an S-regexp)?

This came to my mind because:
- Sometimes one writes an U-regexp in pregexp that shows suboptimal speed.
(This can often be seen more easily by looking at the corresponding
(pretty-print'ed) S-regexp.)
- PCRE has a function pcre_study that proposes improvements. (I haven't
tried this feature in PCRE.)

Greetings
