[Haskell-beginners] garbage collected object

[Ryan Trinkle]

You can use the 'vacuum' package to explore the heap, and you can use
System.Mem.Weak to create a reference to something that won't keep it from
being GCed and will let you check on it later.  You can also use the
built-in heap profiling capabilities to track things like the memory usage
of the entire heap from moment to moment.
