Callable argument conversion error: Cannot convert argument 1 from int to int.

Callable argument conversion error: Cannot convert argument 1 from int to int.

According to the documentation for bind():
When this method is chained with other similar methods, the order in which the argument list is modified is read from right to left.

So the order in this example actually needs to be callable = callable.bind([]).bind(1).

However, it looks like there may be an issue with the error messages: unbind() creates a callable that ignores a number of parameters passed in any future calls to call(). So in this example:

callable.unbind(arguments.size()).call(arguments[0], arguments[1])

the method is not called with arguments[0] and arguments[1] (1, []), but with the previously bound parameters ([], 1), which produces the message about an argument mismatch. However, the error message seems to refer to the (ignored) first argument to call, which actually is an int, so the resulting message is the nonsensical "cannot convert int to int".

In a more simplified version:

func foo(int_param: int) -> void:
    pass

[...]

Callable(foo).bind(1).unbind(1).call('text')
Callable(foo).bind('text').unbind(1).call(1)

The first call will work, while the second will result in "Cannot convert argument 1 from int to int".

Thanks for your explanation, makes it a bit easier to work around this.
