Contract call optimization - remove round trip #944
@carver I fixed the edge case as you suggested, but unfortunately I will not have time to write tests for it.
BTW, what do you think about submitting a feature request to geth/parity to support negative block identifiers? In this case there will be no additional round trips even when block identifier is integer.
Thanks, as soon as someone gets time to add the test, we'll get this merged.
Yeah, definitely worth a discussion.
