Oh, undeniably. It would be a pretty terrible general purpose language -
although the first one isn't massively removed from Java (which is why
Java containers sucked for so long). 

But it might be a useful tool in certain domains, and you could still
use exceptions to provide error handling, coupled with RAII to provided
deterministic resource management.  

RAII is a necessary condition for a language not to suck, but its not
sufficient. :)
