z = condition.ifTrue { 1 + 1 }.ifFalse { 0 } # How?
# If the result is the body of the block the ifFalse could be accidently run by
true.ifTrue { false }.ifFalse { puts "False!" }
# if the result is _not_ the body of the block but rather the condition, it's not an expression
# anymore but a procedural control structure and you have to write
condition.ifTrue { z = 1 + 1 }.ifFalse { z = 0 }
# which is ok I suppose, but not how smalltalk works
