combine
Lib.combine : 'a list * 'b list -> ('a * 'b) list
Transforms a pair of lists into a list of pairs.
combine ([x1,...,xn],[y1,...,yn]) returns [(x1,y1),...,(xn,yn)].
Failure
Fails if the two lists are of different lengths.
Comments
Has much the same effect as the SML Basis function ListPair.zip except
that it fails if the arguments are not of equal length. Also note that
zip is a curried version of combine
