Manually ? Probably...

Worst case meant checking 200+ regexes each time a new one is added.

But it depends on the structure, when de-parsing Perl's internal representation ( use re "debug" ) you'll see that leading and trailing substrings get special treatment.

Anyway... Don't let us waste energy on a XY question. :)
