[Jprogramming] is ! an alternative to ) in explicit def's?

[Brian Schott]

	While poking around I noticed that in pousse.ijs
some of the verb definitions are terminated with ! instead
of ) . For example see the verb run. Is this an undocumented
feature? Does this signal something like recursion?

run=: 3 : 0
q=. a:-.~<;._2 y.,' '
n=. ".>{.q
q=. }.q
n runc q
!
