jello '[e.commit for e in _ if e.commit.author == "Tom Hudson"]'
Has nothing to do with arrays, it has to do with the fact that Python dicts with string indexes and Python objects with properties are different things, unlike JS where member and index access are just different ways of accessing object properties.

This isn't an untyped thing, this is a JavaScript (and thus JSON) and Python have type systems (even if they usually don't statically declare them) and those type systems and thus the syntax around objects are different between the two.
