This is actually a little subtle due to bound variables.

pystring), even though the nodes below x and y will not themselves be equal. This is because
pystring(x) and pystring(y) will not know where these came from and will just compare the uuids.
But pystring on the lambda keeps track of where bound variables were introduced.
