type check should use isinstance instead of type() is #91
Description
I saw all the type check in this libary using type(xxx) is/is not.
I suggest using another built-in function: isinstance.
The main difference here is that isinstance also returns True for subclasses. More details could be found here: What are the differences between type() and isinstance()?
I got a subclass derived from dict, objectpath would raise an error.
change interpreter.py line 44 using isinstance would fix the bug.
def setData(self, obj):
if isinstance(obj, tuple(ITER_TYPES + [dict])):
self.data = obj
