I initialized this repo as a brownie project: https://github.com/darkforest-eth/eth

And went to compile it, only to get the following error message:

AttributeError: 'UsingForDirective' object has no attribute 'typeName'

How can it be fixed?

We need to parse UsingForDirective AST nodes according to this specification: https://docs.soliditylang.org/en/v0.8.13/contracts.html#using-for

I haven't personally used using something for * before, so I will do some thinking about the right way to handle it in the solc-ast codebase. Are you actively maintaining this repo? Do you accept PRs?
