In practice that's the case, that you cannot avoid GC unless you 
don't use anything from the standard library. As soon you use 
arrays, associative arrays and many other data structures GC will 
be used.

There are two options as I see it. Either make the standard 
library not using any GC (likely manual memory management or some 
other method that is not tracing GC), or introduce fat pointers 
where GC objects are of a special type and the you can recompile 
the standard library to the GC type you want.
