I actually have a module partially written that allows one to modify numbered captures.

One problem with changing Perl itself to allow either named or numbered captures to not be read-only, is that Perl is prone to make such captures actually point to a copy of the original string.

FYI, allowing modification of such interleaved substrings is an interesting and rather complex problem (especially the edge cases). But I'll write that stuff up later.

Update: Upon reading more of the thread, I see that what was wanted was to be able to modify a capture variable as a glorified temporary variable. To be clear, what my module does is allow one to modify the numbered capture such that it modifies the string variable that the regex was matched against (while ensuring all of the other numbered captures are properly made aware of the update and, if sanely possible, remain modifiable).
