I'll mention that on top of the time to create a closure (create the
lambda/named function), you also encounter function call overhead. From
all of the profiling tests I've done, a conditional is *much* cheaper
than a no-op function call. AIUI, any function call has to create a
frame, and those take longer than you'd like.
