document that setClass-arg $namspace will be ignored

[staabm]

like we already do in addFunction

@staabm i think this is not a good solution. Either the Parameter should be removed, when it isn't needed anymore, or initial use case of the parameter should be recovered.

There where already an attempt to remove the parameter, but it was reverted, as you can see here:
staabm@2f9afa5

Maybe someone with the knowledge about the history, can suggest, what should be done with the Parameter.

I was trying to make things more consistent. I agree having this functionality implemented would be the best thing but as it stands right now we should document that the parameter doesnt has impact on the method call.

why this actually is the case - I dont know :-).
