It introduces two ways to write the same thing, without much benefit I can see. Your stated goal is to make it clearer that these aren't functions, but language constructs. I'm not sure your change helps that much: While "__halt_compiler()" looks like a function call, "__halt_compiler" looks like a constant lookup. For the declare syntax, "declare(a = 1)" is already illegal syntax for functions, even with the parentheses. Regards, Nikita
