I'm not sure what's your complaint exactly.
Is it that XEmacs' replace-in-string is not standard in Emacs (this
is addressed in Emacs-21 with replace-regexp-in-string) or is it
that you find both implementations of replace-in-string inefficient
(how is it implemented in Perl) ?
Finally, the reason why it took so long for Emacs to provide
replace-regexp-in-string is because Emacs uses buffers a lot more than
strings, so if you need replace-regexp-in-string it's maybe because you
made the arguably wrong decision to use a string rather than a buffer.
Perl is great with strings, Emacs is great with buffers.
