Consider that X = Y; (call this form 1) is exactly the same statement as X = X Y; (call this form 2) "Given that is a legal operator, all C compilers already have code to compile form 2. All we have to do now is modify the compiler(s) to convert form 1 to form 2. This should be utterly trivial, and allows us to add a nice bit of generality to C." This isn't really true. For example, the following two statements have different meanings: X[6*rand()] *= Y; X[6*rand()] = X[6*rand()] * Y; A programmer who codes the first form would not be satisfied if the compiler were to produce the second form. -- Andrew Klossner (decvax!tektronix!orca!andrew) [UUCP] (orca!andrew.tektronix@csnet-relay) [ARPA]
