InvalidOperation on `[[]][i]`

[Sporarum]

On current master (577d253)

@external
def foo(i: uint256) -> DynArray[uint256, 5]:
    return [[]][i]

Fails with either:
legacy:

vyper.exceptions.TypeCheckFailure: assigning Never to Never fake_node fake_node

venom (or legacy with #5234):

vyper.exceptions.InvalidOperation: `Never` does not have an abi encoding

This is most likely a regression over pre-Never behavior
(And should be fixed regardless)

Added as an xfail test in #5234
