[docs] [issue14594] document imp.load_dynamic()

Brett Cannon <brett@python.org> added the comment: I'm fine w/ documenting load_dynamic() and leaving it as-is since importlib uses the function itself (plus the frozen/builtin functions, although the frozen stuff might be simplified since they can probably just return the bytes for the frozen module instead of doing as much work in C code). But load_package(), load_source(), and load_module() need to go. ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue14594> _______________________________________
