Generally, it strikes me as mildly useful. An implementation would surely help :-)

If yours is the most positive review, there probably won't be one. :-)

Seriously, though, I'd readily concede that there are different approaches to solving this problem, and I was hoping for some feedback and suggestions before I start whacking at the code. I also have considered the possibility that although this has been driving me nuts that few others will care--if this is true, it probably shouldn't go in the core libraries.

Presumably 'structmatch' would also become a metho on pattern objects?

Yes. Good point.

[mismatch index return] I don't really like this idea; it seems to be that it would be more helpful to raise an exception and attach this data to the exception. But that's a bit inconsisent with how match and search work.

Hmm. Yeah, if it weren't for the value of matching re.match semantics, it would make a lot more sense for this to be an exception. As it is, I could see it going either way. Or I suppose you could add a flag to determine which (but ugh).

Thanks for your feedback! Mike
