No need to have both if you are returning the receiver.
^ something aMsg ifNotNil: [ aNotherResult ]
For example try printing these two lines1 ifNotNil: [ true ]. "true"nil
ifNotNil: [ true ]. "nil"
If you are interested in the implementation details I highly recommend to look
at the implementation.ProtoObject>>ifNotNil:
aBlockandUndefinedObject>>ifNotNil: aBlock.

Hi guys,
what is the best way to express the following :return (something aMsg) if it is
not nil, return somethingElse elsewhere
I could stil write:
something aMsg ifNil:[^ something aMsg] ifNotNil:[^aNotherResult]
but it sounds a little bit weird
