Have you tried it? That was the first thing I tried.

The problem is that \, converts the sexp that follows it to a string.

Yes, but then you lose the ability to get the current behavior: replace by the
string, "(\"zzz\" \"aaa\")".

IMO, two different syntaxes are needed to separate the two different user
intentions: a sexp that evals to a string "(...)" and a sexp that evals to a
list of strings to pass to `perform-replace'.

For the second case, I think, as I said, that there is no need to provide for a
sexp that evals to the list; it is enough to provide for a literal list. IMO.
