[Pharo-project] numLiterals > 0 is that possible?

Hi guys. Right now we have methodClass "answer the class that I am installed in" ^self numLiterals > 0 ifTrue: [ (self literalAt: self numLiterals) value ] ifFalse: [ nil ] But of course my image has no method with 0 literals: (CompiledMethod allInstances select: [:each | each numLiterals = 0 ]) size -> 0 So...can this really happen? or I can just remove the if ? thanks -- Mariano http://marianopeck.wordpress.com
