[mhh__]

I try to use D for that (difficult because the libraries are fairly low level, I would say sparse but calling into C and C++ is pretty trivial) because, for the same effort I put into bullying python to do what I want, I can write type safe (generic) code that is both actually readable and ready to be reused if needs be. And sometimes orders of magnitude faster.

That and ranges (D/Andrei's preferred model for iteration) are excellent - in my view at least.
