A handful you say.
int, float, str, list, tuple, dict, bytes, bytearray, set, frozenset,
bool, memoryview, object, complex; plus some more in the stdlib such as
deque,; plus some which are technically types but are usually used as if
they were functions, such as slice, range, map, filter, zip, etc. So by
my count that makes at least 15, or 20 if you include the function-like
types.
You must have big hands.
If this bunch-of-attributes object was to move into the std lib, it
would likely become a "core type" and we'd want it to have a short,
simple, all-lowercase name, like the other core types.

The type is not going to be called "ns", that's too cryptic for a core
type. We have "dict", not "dt", "int", not "it", "complex, not "cx". So
you will still be able to say:
ns = obj = o = bunch()
for example.
You always have `from builtins import bunch as MyLongDescriptiveName` if
you disagree.

The established naming conversion for built-in standard types other than
exceptions is all lowercase.
