In C++ regular types have the property that const is deep. If you have a const std::vector<int> the you can't modify any of the integers contained in this container. Naturally for flexibility reasons not all types are regular, pointers being the prominent exception, and things like std::string_view being modern examples of non-regular types.

I feel like you could benefit from watching Scott Meyers about the silliness in C++ if you feel like there’s a consistent and logical feel to the language. A lot of this is c++-isms masquerading sensible ideas through official terms (regular and non-regular types)

		Oh I certainly do not feel like there's consistency in the language. The C++ language is such that everyone picks a subset that makes sense to them and is relatively consistent. Regular and non-regular types are however a basic idea that transcends languages. I can write a snippet in Python too: `import copy from some.random.module.on.pypi import foo a = foo() b = copy.copy(a) assert a == b` If that assertion fails it implies the type isn't regular.
