I don't think so.

std.regex looks like it implements only a deterministic finite automaton, 
whereas what you are looking for requires a push-down automaton. It just 
so happens that a few popular regex libraries implement PDAs rather than 
DFAs (and have associated changes to their regex syntax to make it work, 
albeit inelegantly).
