Because they have to be evaluated only once.
I did consider evaluating them once at the start and saving the values,
but that's a bit problematic from a memory management standpoint.
Still, if you have a good solution to that and the cycles to produce a
patch, it's not too late to reconsider. I concur that it's not that
hard to think of cases where it'd be useful.
