A tuple can have any number of elements. (1,2) is a 2-tuple. (1,2,3) is a
3-tuple. (x:xs) and (x,y) are differently typed: xs must be a list of the
type of x, while y can be any type. (x:xs) is not a tuple. It is a list by
definition.

Hello Xiao,
(one_element) -- is evaluation (element,element,...) -- is tuple
(1:[2]) -- [1,2] because it is one "array element" (1,2) -- is a tuple because there are 2 elements _______________________________________________ Beginners mailing list Beginners@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/beginners
