??

I'm not sure I follow.  The /o option simply tells perl not to
recompile a regex that contains interpolation strings more than
once.

If you don't have something like s/$pattern/subst/o, what purpose does the 
/o serve?  Perl isn't going to compile your pattern more than once anyways, 
so why make the reader wonder?

If you want to insert useful explicit documentation, you could use the /x 
option and put comments in, but this substitution is too short to need that.
