scope of variables in loops

["Joey Mingrone" <joey@xxxxxxxxxxxx>]

Hello,

Unlike bash, parameters that are set in loops on the command line
stick around.  It's not a big deal once you figure out what's going
on, but the code below can cause some head-scratching.  Is this
intended?  Is it controllable (is there a way to turn it off)?

Thanks,

Joey
