Yes, we'll probably need an easy way to distinguish truely, absolutely fatal
stuff (out of memory or some other sort of runtime error by the 
interpreter) from ordinary exceptions.

I'm not sure though wether I like the usage of die to throw fatal 
exceptions vs. throw for possibly non-fatal exceptions, especially 
considering the fact that many modules currently use die for trivial stuff 
like reporting wrong parameters...

A better way would probably be to use different base classes, like 
Exception for an exception which might be a problem but not very serious 
and Error for the real, usually always fatal problems.
