What you have is a syntax error interactively.  It should work in a
program (the backslash is a no-op in a string).  /)$/ is good enough
and works in both interactive regexp search and in a program (unless
you need to match the whole line, in which case /^.*)$/ is what you
want (AFAIK Emacs doesn't guarantee longest match even today; I think
you can omit the "^" here, but I'd need to read the source to be
sure).

Sure, but your blockage is that you aren't using Emacs REs, you're
trying to use some other kind of RE.

I think you might be helped a tiny bit by rawstrings, but I have to
admit that Stefan is right in your case: the problem is not the
proliferation of backslashes, it's that Emacs has a unique and
comparatively awkward syntax for regular expressions.  Rawstrings
might make it a little bit easier for you to adapt, though.
