I think there was a discussion some time ago that self might not
have been the best default return value. YMMV.<br>

+1. Senders might want to cascade.

I prefer the first - it gets one case out of the way quickly.

Hi,
I'm about to write a method where I need to test whether to do something or
just get out. What is the best practices way to do this? For example:
(a = b) ifTrue: [^nil].
*The code that does the work*
or:
(a = b) ifFalse: [
*The code that does the work*
].
I think the second is better style but I have used both. Generally using
the first when *The code that does the work* is long and the second when it
is short.
Is there any speed difference between them? I doubt it but I thought I
would ask anyway.
