http://rosettacode.org/wiki/Handle_a_signal

Most general purpose operating systems provide interrupt facilities, sometimes called signals. 
Unhandled signals generally terminate a program in a disorderly manner. Signal handlers are 
created so that the program behaves in a well-defined manner upon receipt of a signal.

For this task you will provide a program that displays a single integer on each line of output at 
the rate of one integer in each half second. Upon receipt of the SigInt signal (often created by the user typing ctrl-C) 
the program will cease printing integers to its output, print the number of seconds the program has run,

// Examples

var set = AnySet()
set.insert(3)
set.insert("hello")
set.insert("hi")
set.insert(2.3)

set.contains(6) // -> false
set.contains(3) // -> true
