I'm not sure it helps with compiling to C or C++ (that is neither
necessary nor sufficient for being a high performance language), but it
has the potential for helping quite a lot with performance. If you read
stuff written by evangelical Common Lisp folks, they tout CL's optional
type annotations as providing a mechanism for getting near-C-like
performance. I haven't tested that myself though.
