Yes, indeed part of the work is already done and part of the GNU sed
tarball (search for REG_PERL). Though the option was -R, not -P.
I want to release a new version of sed this August (it is time!) and I
would love to include this functionality on it. I think it is not too
late to use -P instead of -R, to keep some uniformity with the other
tools.
