You summarise well the kind of code I do not like.
isNil everywhere and horrible tests.

Hi guys,
I’ve started to use this little one:
Object>>ifNilOrEmpty: aBlock
self ifNil: [ ^ aBlock value ].
(self isCollection and: [
self isEmpty ]) ifTrue: [ ^ aBlock value ].
^ self.
It allows you to do the widely known JavaScript one-liner:
var stuff = this.thing || ‘some default value for when this.thing is undefined,
null or an empty string’.
but in smalltalk in this way:
stuff := self thing ifNilOrEmpty: [ ‘some default value for when self thing is
nil or an empty string’ ]
simple thing feels practical and nice :)
