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 :)
