"""Fallback primitive operations that operate on 'object' operands.
These just call the relevant Python C API function or a thin wrapper
around an API function. Most of these also have faster, specialized
ops that operate on some more specific types.
Many of these ops are given a low priority (0) so that specialized ops
will take precedence. If your specialized op doesn't seem to be used,
check that the priorities are configured properly.
