Well, this was of course just a wild proposal without any serious
thought behind the involved details.  One should probably take a look
at eshell syntax maybe for getting some suggestions for a somewhat
consistent syntax, and one would need to think about a way that makes
it possible to end the expression in question without adding
unnecessary spaces or so to the match.

And of course, this sort of stuff should not be done by replace-match
or similar functions but just by the interactive function, to avoid
opening security concerns when Emacs is used as a match-and-replace
engine (where people don't expect it to execute arbitrary code).
