# The docs say we should use register a function to determine the numba type
# with `@numba.extending.typeof_impl.register(MultiVector)`, but this is way
# too slow (https://github.com/numba/numba/issues/5839). Instead, we use the
# undocumented `_numba_type_` attribute, and use our own cache. In future
# this may need to be a weak cache, but for now the objects are tiny anyway.
