 I don't care much about the compiler - but I don't think this is an improvement for the programmer.  (In general, I dislike trying to do too much in a single expression or statement, but some C constructs are common enough that I am happy with them.  It would be hard to formulate concrete rules here.)
 And the resulting object code is less efficient than you get with signed int and "y = p[x++];" (or "y = p[x]; x++;") in C.
