inline if in Smalltalk

No! No! No! Dont extend Smalltalk with things like that.

Just because you can extend Smalltalk does not mean you should do on all ends. So unlearn your traditional syntax thinking before starting with it. Code should tell a story to be maintenable and not end up in deciphering cryptic syntax sugar.

Lets think in objects and stay readable with: #ifTrue;ifFalse: please!
