Sorry, I didn't have time. I have now.
I've started to work my way through your email. I'll reply to specific
points in subsequent emails as a work further along.

This is actually a more fundamental regression in 5.18.0, that doesn't
require any use of overload etc; just a '#' within a character class in an
extended regex stops code blocks from being parsed:
$ perl5180 -e'/[#](?{})/x'
Eval-group not allowed at runtime, use re 'eval' in regex m/[#](?{})/ at -e line 1.
$ perl5180 -e'use re "eval"; /[#](?{})/x'
Eval-group not allowed at runtime, use re 'eval' in regex m/[#](?{})/ at (eval 1) line 1.
Fixed now in bleed with c30fc27b4df65a43710b25dd1d2a57d78ee2fe33.
This is a strong candidate for back-porting to maint-5.18.
