Rename unsqueakish parameter names

[Paulpanther]

Some parameter names, like in for: username using: password should be renamed. There should be an a before the parameter name and it should declare its type and not its interpretation. But since both parameters are String we cannot have aString and aString. What is the correct/squeakish way?

imho for: aUsernameString using: aPasswordString if the datatype of the parameter is not obvious. In this case I'd suggest aUsername, aPassword.
But parameters like data are used in our codebase as well. Those could be instances of ICEndpoint, Dictionary, Collection or whatever.
In those cases the datatype should be explicitly named
