Creating services

[Marcus Denker]

Hi,

I don't think that this has been changed.

perform: selector orSendTo: otherTarget
	"If I wish to intercept and handle selector myself, do it; else send  
it to otherTarget"
	^ otherTarget perform: selector

sw 10/30/1998

But we had already multiple people requesting this to be changed in a  
way that it
does what the selector says:

http://bugs.impara.de/view.php?id=1666

perform: selector orSendTo: otherTarget
	"If I wish to intercept and handle selector myself, do it; else send  
it to otherTarget"
	^ (self respondsTo: selector) ifTrue: [self perform: selector]  
ifFalse: [otherTarget perform: selector]! !

The only pronlem was that, hehe, the wrong code was there by design,  
this bug report was done multiple
times the past and allways rejecte by SqC.

I tend to just implement the method that it does what it says and see  
what will break.

       Marcus
