Casting parameters to custom LoadFunc (was RE: Restricting loading of log files based on parameter input)

[Stevens, Ian]

One quick question:

> A = LOAD '/foo/replace_me_with_regex' USING MyLoadFunc('2013', '1', '28');

Is there any way to use script parameters here and cast them to int? In other 
words, can LoadFunc constructors only accept Strings?

These do not work:

        A = LOAD '/foo/replace_me_with_regex' USING MyLoadFunc($year, $month, 
$day);
        A = LOAD '/foo/replace_me_with_regex' USING MyLoadFunc((int)$year, 
(int)$month, (int)$day);

This does, but it forces my LoadFunc to accept String parameters and do the 
casting within:

        A = LOAD '/foo/replace_me_with_regex' USING MyLoadFunc('$year', 
'$month', '$day');

Thanks,
Ian.
