Generate a random whole number without consuming a rand

rand_i_look  max (number_or_range)

Given a max number, produces a whole number between 0 and the supplied max value exclusively. If max is a range produces an int within the range. With no args returns either 0 or 1.

Does not consume a random value from the stream. Therefore, multiple sequential calls to rand_i_look will all return the same value.

Introduced in v2.11
