I am wondering why this function should not work with input [x,y] (list with two elements) too, since third element is not referenced.
What a pattern matches is independent from which of the variables it binds are used. The pattern [a,b,c], or equivalently a::b::c::[], matches lists of length 3. You can write a::b::_ to match all lists of length 2 or more. -- __("< Marcin Kowalczyk * qrczak@knm.org.pl http://qrczak.ids.net.pl/ \__/ ^^ SYGNATURA ZASTÊPCZA QRCZAK
