This solution looks crappy to me:
void gc_collect(void *unused = null);
BTW, any compiler with alias analysis and LTO might even decide to
remove the call even with the unused parameter, since it, well, isn't
used. I think we need a language-level solution here.
The LTO would have to be able to make decisions at link time based on
purity, because the call *does* do things, it just doesn't use the
parameter. I have no idea, maybe you are right, it would be a hard
problem to fix if this happened.
