Think about it from the parser's point of view. It has to evaluate $client->system to determine the parameter list for multiCall(). Then it has to evaluate those parameters before it can stuff their values into the stack so it can call the function. But, whether it evaluates the parameter list left-to-right or vice versa is implementation dependent. I don't believe you can rely on it always being the same unless you always use the same interpreter.
