Right. Even Java does not do that.

Numba will compile the Python overhead out of function calls, if that is 
what you mean. Numba will also accelerate Python objects (method calls 
and attribute access).

LLVM knows how to do simple optimisations like function inlining. When a 
Python function is JIT compiled to LLVM bytecode by Numba, LLVM knows 
what to do with ut. If the function body is small enough, LLVM will 
inline it completely.


Numba is still under development, so is might no be considered 
"production ready" yet. Currently it will give you performance 
comparable to -O2 in C for most algorithmic Python code.
