Secondly, as of today what do y'all do when you need that functionality
I can only speak for myself, why I do not miss regex substitution too much.
Sometimes, regex substitution is exactly the solution, and I use it. But
the whole job is easily done in a shell script, or even in an editor. So
I don't use regex substitution in Haskell in this case.
Sometimes, the substitution job is: transform this
<article>
<title><code>Monad</code> Tutorial</title>
<content>...</content>
</article>
to this
<!DOCTYPE html etc etc>
<html>
<head><title>Monad Tutorial</title></head>
<body>
<h1><code>Monad</code> Tutorial</h1>
...
</body>
</html>
In this job, if a regex solution exists, I don't want to know. I just
use HXT or XSLT.
Sometimes, regex substitution plus Haskell is exactly the solution. Then
I use regex-compat. It works. One solution is enough. I don't need a
hundred choices for regex, or a hundred choices for Int.
