combine : 'a list * 'b list -> ('a * 'b) list
STRUCTURE
SYNOPSIS
Transforms a pair of lists into a list of pairs.
DESCRIPTION
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
