I think in Lisp programs it's much easier and more problem-free to evaluate Lisp expressions normal Lisp-way than to write expressions inside strings and use the "\\,expression" form there. Interactive replace string \,(capitalize \1) can be written as (capitalize (match-string 1)) in programs. With functions like "concat" or "format" the latter expression can be concatenated with the surrounding replace string.
