I'd like to merge #1657 first and rebase on that to ensure we're playing with all the latest toys

Not sure I understand the fix here, as far as I can tell all these types are replaced by Constant(value=) now, doesn't that mean we have to translate each constant type and port over the value attribute (e.g. .s for Str and .n for number) ?

And would that mean something the replacement step would have to map something like isinstance(node.value, str) => vyper_ast.Str(s=node.value) (if isinstance(node, python_ast.Constant).

technically, eth-tester (and py-evm) doesn't support 3.8 yet. That could be why this is an issue.

Ahh, it looks like it's the blake2b-py build that's not compatible somehow. cc @davesque
