I should have mentioned also that ANY makes a nice "or" condition:
ANY [ this or-this or-even-this or-finally-this]
reduces each expression it encounters through the block not stopping until
it exhausts all the expressions
or it encounters one that results in a value that is not NONE and not
FALSE.
So
ANY [1 = 3 now 3]
will return the current time
