Make ArrayValue not callable #728
Description
Some Python libraries can accept either a function or array, and distinguish between the two with isinstance(x, typing.Callable). Unfortunately this is always the case for ArrayValue:
Which means that libraries may try to treat the array as a function. Would it be possible to fix that? I'd guess that ArrayValue would need to stop inheriting from AnyValue, which defines __call__().

Unfortunately that would be a breaking change, because it's documented to inherit from
AnyValue.However I think this is fixed on the v1 branch. AFAIR
Jl(what wasAnyValue) andJlArray(what wasArrayValue) now both inherit fromJlBase, which has very little functionality, and onlyJlhas__call__.Please try it out and report back.

Thanks, indeed it's fixed on v1. Unfortunately v1 somehow breaks the real example, but that's probably a different issue :)
