What programming language is best suited for a miner?

I'd think some low level Assembly in C would be very good, but what about a faster scripting language like Python.

I'd have to assume OpenCL/CUDA and a cURL library would need exist for said language as well.

Then there is x-platform support to consider as well...

All of the hard work is done in OpenCL kernels anyway, so unless your language's OpenCL libraries suck I don't see why there would be much of a difference.
