To be clear: the @ does NOT change the result of the function in any way
(so it has no effect on whether or not the above if() block is entered). It
only squelches warning/error(?) output.
It can also be used on methods: @$obj->foo(). It cannot be used with
function-like keywords, e.g. @isset() doesn't work IIRC.
