I am looking for a substring replacement based on Perl like regular expressions that would let me use part of the original string in the replacement string. Something like:

reReplace "name is (.*)\\." "hi \1!" "my name is john."

which would result in

"hy john!"

It's not exactly what you're looking for, but I'd simply do something like this, using Text.Regex.TDFA or any other:

let [[_, name]] = "my name is john." =~ "name is (.*)\\." in "hi " ++ name ++ "!"

Thanks for the tip. It was useful to solve my original problem. Romildo
