Checking for Nones based on an arrays type

[maadcoen]

I have a collections of arrays of different types, and I want to assure the content does not contain any None values.
I understood that an array that can contain Nones has this reflected in its type by a question mark. So it's seems like it is not necessary to perform ak.any(ak.is_none(ARRAY)) on every single array. However, I couldn't find a way to properly inspect the type of an array like this, except for doing "?" in str(ARRAY.type), which feels rather clumsy to me.
Is there a better way of doing this?

ARRAY.type is a data structure with content (single child, another Type) and contents (multiple children, a list of Types) that can be navigated.

It's best to avoid checking for a "?" in the string because in more complex cases, the function name option[...] is used.
