D without a GC

As stated in this proposal they are quite useless, e.g. they are easily 
implemented via mixin with alloca.
Plus, what's the benefit in throwing exception on alloca failure, how 
you suppose the user to handle this stackoverflow exception? I would 
have expected a better design to provide an optional parameter to 
fallback to GC or something ( like malloc(...) + scope(exit) free(...); 
) and that's indicates a library solution, of course.
