I read the perldoc that far ;-)
and decided I don't need -T, as I'm checking all input with a regexp not as general as (.*). I had used -T, but really found no difference, so I left it out, as there must be some impact on runtime.

So unless taint-checks do check more than I know, I think I don't need it here.

Edit: Don't get me wrong.
Please convince me that I need -t or anything else I might have missed.
I'm doing a lot of stuff in perl, but I'm mostly paid to do java.
