Here's my first (simple) testcase:

The steps needed to compile and test it are a bit obscure right now,
because you have to explicitly link in the GC runtime.  I expect that a
GC'd language front-end would probably just link the GC into its standard
runtime to make this nicer (or hide it in the compiler driver).  In any
case, when I finish up the GC doc, I will include instructions on how to
do simple tests.  :)
