> Common practice programming languages like Go are getting into the 1980s or so, research-wise. The Haskell community is into the 90s, along with some genuinely new stuff. Both have a long way to go before they're accepted common practice.

Rust actually uses new stuff; the borrow checker builds on old ideas from Cyclone and others from the 90s, but it mixes it with some interesting research ideas of its own (using C++ destructors to get region typing at the level of individual values, not of regions) to come up with something that's actually fairly novel.

Well, I hardly set out to show the entire range of new stuff in two paragraphs... :) But I'd also observe that Rust has a ways to go before being common practice, too. More power to you, for the love of all that's holy please put a bullet in C and C++, but even in the best case scenario you're still at least three or four years away from even being solid B-list (Perl, Python, etc... Go isn't there yet either, FWIW).
