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.
Can you point me to terminology other than the c++ spec (preferably literature) that defines regular types? I can only find references to this concept in c++ land.
I think this terminology was originally invented by Stepanov. And he used C++ to explain the concept. That's why you can only find references to this concept in C++ land.
