How best to write this if-else?

[Mike C. Fletcher]

Hmm, what does Perl do when there's multiple threads using the same re
concurrently?  I think that's the major reason behind the matchobject
approach that arrived with the re module (the older regex module uses a
pattern similar to what you've described).

Enjoy,
Mike

This allows the perlish idiom:

if p.m(regexpr_here,data_string_here):
    prematch=p.PREMATCH
    match=p.MATCH
    postmatch=p.POSTMATCH
    group1=p.S1    # S = $
    ....
