* If PY_LOCAL_AGGRESSIVE is defined before python.h is included, a more
* "aggressive" inlining is enabled. This may lead to code bloat, and may
* slow things down for those reasons. Use with care.
*
* NOTE: You can only use this for functions that are entirely local to a
* module; functions that are exported via method tables, callbacks, etc,
* should keep using static.
