For writing interpreters, RPython spanks C.
What's RPython doing that makes it faster?
Allowing PyPy to have a good JIT compiler.
I don't understand. Does that JIT generate faster code than a C
compiler would generate?
I don't know, but my wild guess is that a JIT optimizes the *right*
hotspots based on real-time performance measurements, whereas a lot of C
programmers are obsessed with optimizing what they *think* are the
hotspots, but which really aren't.
I meant what the C *compiler* generates.
