This completely removes the code, using dead code elimination, at compiletime:
when conditionThatsRarelyTrue: discard
For runtime alternative, compiler uses branch optimization:
if unlikely(conditionThatsRarelyTrue): discard elif likely(conditionThatsUsuallyTrue): discard else: discard
The likely() will be faster, the unlikely() will be slower. This is Nim lang.
