volatile is not a storage class, it's a cv-qualifier like const.
And in fact in C you could also omit the storage class and specify 
just the cv-qualifier:

main()
{
   volatile i = 0;
   const j = 0;
}

If we allowed this for the proposed implicit typing scheme then given:

void foo(std::string s)
{ 
   const t = s.c_str();
   ...
}

Would the type of t be const char* or const char* const? (I would 
have thought the latter).

Also it's not clear whether specifying the storage class after the cv-
qualifier is allowed (Comeau online gives a warning).

extern is the other storage class, which can only be used to 
initialise a variable outside of block scope.
