[issue22493] Deprecate the use of flags not at the start of regular expression

[Ales Kvapil]

Ales Kvapil <aleskva at mailinator.com> added the comment:

Maybe there should be introduced some method to merge patterns as just piping patterns will not work:
pats = [r'(?m)^line.continues$', r'(?s)begin.*?end']
re.compile('|'.join(pats))
