Exceptions and memory allocation are a pain to use anyway. When 
you call a function that calls a function that calls a function, 
and you get an Exception, how do you know how to properly 
deallocate it ?

And it's not just the Exception Object itself, usually you also 
have to allocate at least a string for the Exception message.
