Fixes: #2113
What I did
Solidity returns the members or components of a struct/tuple when it is the only thing being returned (as a gas-saving measure). This lead to some minor incompatibilities with Solidity, and there was a strange bug in our test suite that I believe was introduced in v0.2.0. Unsure if this issue persisted before, but I believe it to be a minor issue that is easily worked around by changing the ABI that Vyper outputs in those rare circumstances where the ABI was inconsistent with the encoding.
How I did it
inserted one line into
vyper/signatures/function_signature.pyHow to verify it
Had to update several tests that returned a tuple instead of a list from
eth_abiDescription for the changelog
Return tuple members directly if they are the only return value
