Examples and tests should require a lot less boilerplate using Numba's new mutable structures.

operator.is_(Opaque, Opaque) will be in Numba 0.51 and there should not be a duplicated implementation here ( see 5834).

Move to typed.List?

Checking the exception message in TestPassThruContainer.test_eq_any seems to be depending on locale/OS.

Originally reported by @eric-wieser here.

The current behaviour in nopython mode is False == (container == any_other_type) and any_other_type == container raises a TypingError.

PassThruContainerType.__eq__ should only cover comparison of two PassThruContainerTypes and fallback to generic eq in any other case like returning NotImplemented from the __eq__ implementation on the Python side. However, Python's fallback behaviour for classes is object.__eq__ which is operator.is_ and hence is different from Numba's generic eq.

container == any_other_type and any_other_type == container should raise NotImplementedError when called from Python and raise TypingError during compilation. This seems to be the most consistent behaviour achievable.

The renaming of builtin numba modules leads to the following issue:

>>> import numba_passthru
ImportError: cannot import name 'cgutils' from 'numba'
