Interface implementation enforcing units?

What's your issue about?

Compiler erroneously enforcing units on interface method returns

• full output of the error you received:
  vyper.exceptions.StructureException: Contract does not comply to supplied Interface(s).
  Missing interface functions:
  ... ( any method that does not match the return unit. Returning wei_value vs uint256 for example )

• what command you ran: vyper

• the code that caused the failure (see this link for help with formatting code)

  @public
  @constant
  def balanceOf(owner: address) -> wei_value:
  return self.balances[owner]

How can it be fixed?

Thanks @robrobbins ! I think we should just fix it - ABI can't specify units - so unit checking at this level should be ignored.
