"moonworm generate-brownie" does not deduplication argument names of method arguments with meta-arguments

[zomglings]

Example with block_number as a view method argument:

    def get_block_hash(
        self, block_number: int, block_number: Optional[Union[str, int]] = "latest"
    ) -> Any:
        self.assert_contract_is_instantiated()
        return self.contract.getBlockHash.call(
            block_number, block_identifier=block_number
        )
