I like the way you disable all warnings. :-) But, why? (I have some ideas, but I ask just to be sure.)

    But, why?

    That code was typed straight into the web page and not tested. In general if you have an isItSomething() routine returning a bool, you don't want it to produce any warnings, just return false if what you've been passed isn't what you're testing for.

    The fact that there appears to be nothing you can give to ref that produces a warning means it is probably redundant.
