Best way to create a node dictionary

[Kludex]

Hi there 👋

I've found different use cases on which I need a dictionary, with the key being a CSTNode. Because of...

LibCST/libcst/_nodes/base.py

Lines 429 to 441 in bd5ede7

	def __eq__(self: _CSTNodeSelfT, other: object) -> bool:
	"""
	CSTNodes are only treated as equal by identity. This matches the behavior of
	CPython's AST nodes.
	If you actually want to compare the value instead of the identity of the current
	node with another, use `node.deep_equals`. Because `deep_equals` must traverse
	the entire tree, it can have an unexpectedly large time complexity.
	We're not exposing value equality as the default behavior because of
	`deep_equals`'s large time complexity.
	"""
	return self is other

What's the recommendation in this case? Do I need to create my own Mapping class?
