Does not it support contract inheritance and 'using' grammar?

I want to test my contract file, but it does not work if contract has a 'using' syntax or if contract inherit a contract.

Are you using objectify? Because I have the same issue but only when I try to objectify the result of parse_file. As a workaround I've been using the result of parse_file as is.
What I've found is that this parser mistakenly labels "usingForDeclaration" under "name" instead of "type" which is inconsistent with other declarations in this parser and Solidity ast-compact-json output. The exact same thing applies to "InheritanceSpecifier" in base contracts.
Considering I'm getting KeyError: 'type' errors in both cases I think this is the source of the issue.
