You can get almost everything to work, though some built-in 
features will need to be replaced/supplemented by library things 
and some care will be needed to avoid memory leaks.

Specifically:

* the a ~ b operator is a bad idea without the GC. (and with the 
GC in performance critical code)

* delegate closures are a bad idea without the GC (though you can 
make them work)

* Your classes will be written pretty differently

* ~=, .dup and .length on built in arrays will need to be 
replaced by a library thing


I think the rest can be made to work off the top of my head. 
Though, I think the cases where you want to go without the GC 
entirely are pretty rare. Normally, I'd just be careful about 
where you trigger it instead.
