Is there any way to use backreferences _within_ a _pattern_, as works on
some regexp parsing applications, i.e.

'<a href="mailto:([^@]*)@([^"]*)">\\1@\\2</a>'
=>
'\\1@\\2'

so that
<a href="mailto:foo@example.com">foo@example.com</a>
WOULD match and be replaced by foo@example.com

but
<a href="mailto:foo@example.com">bar@example.com</a>
WOULD NOT match (and thus no replacement take place)

?

I can't seem to get this to work. Any suggestions for an alternative?
