I'm sorry, I don't agree. It's clear that the first value printed will always be 3. But the spec does not guarantee when the second argument to p is evaluated. It may be evaluated before call of f, in which case the program will print 1, or it may be evaluated after the call of f, in which case the program will print 2. The spec does not actually say that all function call arguments are evaluated in left to right order. It says that among the arguments, all function calls, method calls, and communication expressions are evaluated in left to right order. That is not quite the same thing.
