Set<a> newSet(Int(a, a) cmp=compare)
Arguments
cmp: The comparison function to use for ordering. It must take two parameters, returning a negative number if the first parameter is smaller (whatever 'smaller' means in this context), positive if it is bigger, and zero if the two parameters are equal. For Ints, for example, the functionInt icmp(Int a, Int b) = a-b;could be used. This argument may be omitted and defaults to Builtins::compare.
Usage
Create a new empty set.
