Pattern matching broken

[henryiii]

The following MWE fails on GraalPy, but works on CPython:

x = sum
match x:
    case object(factor=x) if x is not None:
        print("Has non-None factor")
    case x if callable(x):
        print("Callable")

CPython:

Callable

GraalPy:

Traceback (most recent call last):
  File "/Users/henryfs/git/scikit-hep/boost-histogram/tmp.py", line 3, in <module>
    case object(factor=x) if x is not None:
AttributeError: 'builtin_function_or_method' object has no attribute 'factor'
