It's similar, but a list of chars that need escaping is more flexible.
I could specify that '(' needs to be escaped to mean grouping and that
'?' does not need to be escaped to mean optional. Using the list could
be dependent on the "magic-ness of a pattern".
Hm, interesting concept. Attached is a simple script to try out.
Use
:let g:re_dont_escape = '()|?'
to specify which chars have a special meaning and don't need to be
escaped (only for using the literal version). So in this example, '()
wouldn't need to be escaped for grouping, '|' means OR and '?' means
optional match.
When searching, press<f7> to translate the pattern into a vim pattern.
It basically only adds/removes the backslashes (so you need to know all
vim specific atoms, like '\@<=' and can't use e.g. Perl look-arounds).
Disclaimer, only very basically tested.

Thanks Christian and Andy.
I'm on vacation now, won't be giving this any play until after next
week. But it looks like some pros are working it over.
