anything)
There's always claims that systems like RPython, or Haskell, or
LuaJIT, or Java HotSpot are able to rival or beat C, yet all I
ever see are small toy programs. Show me something big.
Something with 100's of thousands of lines of code.
If all this is true, where are the video games written in these
languages that rival performance/fidelity of AAA titles? I've
never seen that. Ever.
Rpython has been used to write a very fast jit (pypy) which is
not the same as an interpreter. The interpreter is what you fall
back to when you can't use the jit.
I don't know how fast pypys interpreter is specifically, but it's
not it's main selling point.
