Is it possible to do substitutions with PGE yet? If so, how?

Single (first occurrence) substitutions are possible; simply perform
the match, the match object returns the start/end location
of the item that matched, and then do a substr operation based on
that information.
Performing multiple substitutions doesn't exist yet in pure PGE;
eventually we'll have the ":globally" option available, in this
case the match object will have a .matches method that will
return the array of items that matched, and one can perform the
substitutions on that (presumably in reverse sequence so as to
not interfere with offsets too much).
