You mean homogenous instead of heterogenous, right?

  To add to this, arrays are also restricted to primitive C types. A Python array object is simply a heap allocated `unsigned long *` or what have you. https://docs.python.org/3/library/array.html https://docs.python.org/3/library/array.html https://github.com/python/cpython/blob/main/Modules/arraymodule.c https://github.com/python/cpython/blob/main/Modules/arraymod... And you can use struct for heterogenous data =) It has a neat DSL for packing/unpacking the data, reminiscent of the "little languages" from classic book The Practice of Programming. Python is actually pretty nice working with binary data. https://docs.python.org/3/library/struct.html https://docs.python.org/3/library/struct.html

    > Python is actually pretty nice working with binary data. It really is! I’ve been working on a project to generate large amounts of synthetic data, and it calls out to C for various shared libraries to do the heavy lifting *. Instead of encoding and decoding back and forth, I can just ship bytes around, and then directly write them out to a file. Saves a lot of time. *: yes, I should just rewrite it into a faster language entirely. I intend to, but for the time being it’s been “how fast can I make Python without anything but stdlib,” as long as you accept ctypes as being included in that definition.

  Ugh… yes. Thank you.

  It would be very funny to have an iterable type where the items are required to contain incompatible types.

    Somewhere out there, I'm sure someone could come up with a use case.
