Upcoming _hyperscript feature: Waiting for an event

hyperscript 0.0.4 beta is going to be out soon

a sneak peek:

the wait command can now pause evaluation until an event is received

here a class is added, hyperscript waits for the transition to end, then the element is removed

feature suggested by @DenizAksimsek
