Doesn't matter. The argument is actually both already. If you
reference it without a scope, it's a local variable. If you reference
it with the 'arguments.' qualifier, it's an argument. And yes, there
really is two copies of the string accessible in your function.
That's also why you can't declare a local variable with the same name
as an argument: it's already declared implicitly by CF.
I personally NEVER use the arguments qualifier, thereby ensuring that
I'm always dealing with the local variables. It's easier to spot
"arguments." where it shouldn't be, than it is to spot a missing one.
You do have to use the arguments scope for structKeyExists calls for
non-required args that don't specify a default, but that's the only
place you need it, at least in my book.
