As for the back-refs and recursive parse, that's going to be more in demand, not less. For example .NET implementation of Perl regex was designed to be able to parse XML without a perf hit and while I couldn't say if Perl would take a perf hit for something like that, it definitely can parse XML with regex much easier then .NET.

Im not sure what performance hit you mean. Although ambrus had some neat ideas for something like the super-linear cache with regards to pattern level recursion that i have yet to follow up on.

Also juerd has published a validation regex for xml that is derived from the EBNF that w3 has posted. The story that you cant parse XML or HTML with regexes is going to go up in a puff of smoke when Perl 5.10 comes out.
