Make `ArrayValue` not callable

[JamesWrigley]

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 was AnyValue) and JlArray (what was ArrayValue) now both inherit from JlBase, which has very little functionality, and only Jl has __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 :)
