Cool.

Allow me:
{ std::map<std::string,std::string> bar;
bar["some key"] = "some value"; if (bar.find("some other value") != bar.end()) ... }
Works beautifully, all you need is to pick the existing language which allows for the existing standard library which already provide that functionality.
I doubt there's much need for a C+ or C 2+/3 langauage variant ;)

Ok, I can't help you with that.
You have probably seen a Perl program before... Now imagine a two million line Perl program... That is why the above is not a good idea ;)
It's still your right to want it of course...

Built into the language (not a library)?

If you look at http://www.codesourcery.com, you can see that there really are some people who do GCC extentions or optimizations for money - various institutions have funded additions to GCC this way.
It's a cool idea - I have a few things I'd like my company to fund as well... Some time in the future... Unless someone beats us to it.
