Re: [Pyobjc-dev] Possibly dumb question

[<bb...@ma...>]

It eliminates an ambiguity for methods that take no arguments vs. one 
argument.

I.e. there is a difference between this...

     foo.doSomething()

...  and this ...

     foo.doSomething( bar )

The first is the method 'doSomething', the second should be 
'doSomething:'.   While we could have the bridge count the args and 
silently fix the second case, such actions generally lead to ambiguity 
and confusion -- and, potentially, maintenance nightmares.

In any case, that final '_' is useful in that it gives immediate 
indication that "Hey, I'm writing this method or call that method very 
much in light of the presence of Objective-C".
