1. Quicksort

Here is Hoare's quicksort using sequence comprehensions:


bar(xs as Seq of Integer) as Seq of Integer
~  return xs
qsort(s as Seq of Integer) as Seq of Integer
~  if s = [] then
~    return []
~  else
~    pivot = Head(s)
~    rest = Tail(s)
~    return qsort([y | y in rest where y < pivot]) +
~            [pivot] +
~            qsort([y | y in rest where y >= pivot])

A sample main program sorts the Sequence [7, 8, 2, 42] and prints the
result:


Main()
~  WriteLine(ToString(qsort([7, 8, 2, 42])))

The call to ToString is just to work around a current problem in the
AsmL2 compiler.
