twistedchecker requires camel case even when overriding a method signature.

[wsanchez]

If you are implementing a callable that is meant to have the same signature as a callable in the standard library (or another library which does not use camel case), then twistedchecker will complain.

Because twistedchecker is a required test in Twisted, that means you have to change the signature, which may means it is not compatible in the way intended.

This is a duplicate of #76

[wsanchez]

#76 is for method names. This is for arguments, specifically arguments that comply with a non-Twisted interface.
