(synopsis "Compile Python code using LLVM")
(description "Numba gives you the power to speed up your applications with
high performance functions written directly in Python. With a few
annotations, array-oriented and math-heavy Python code can be just-in-time
compiled to native machine instructions, similar in performance to C, C++ and
Fortran, without having to switch languages or Python interpreters.
Numba works by generating optimized machine code using the LLVM compiler
infrastructure at import time, runtime, or statically (using the included pycc
