curry.backends.py.loader module
Loads a generated Python module into an interpreter.
The module is loaded through importlib, so CPython’s bytecode cache applies:
a valid cache beside the file (__pycache__) is read instead of the source.
The cache is a product of the toolchain, like the file itself, not a by-product
of an import. The toolchain writes it when it writes the file (see
Json2Py), and the loader writes it when it finds none or a stale one, with
or without -B. So a generated module is compiled from source at most once
per change, not in every process. Compiling the generated Prelude from source
costs about 0.2 s; reading its cache costs a few milliseconds.
