even so wouldn't the original string need to be copied if it was being
modified so $& would be aliased correctly to the old data? in the case
of m///, $& should (and according to mjd is) be be aliased directly into
the original string as there is no copy made.
so the /k option would only be added to s/// as a way to force a copy of
the original string and alias $& to it.
and $& is local to the block. i assume lexically but is there any
argument for localized?
