in reply to capture STDOUT when some jerk opened STDOUT to /dev/tty

Why not fake modifying the script by using do?

select MYSTDOUT; # use *MYSTDOUT instead of STDOUT for output # so all his reopening manipulates the wrong filehandle # Run the original script in our interpreter do '' or die;

Update: Also, you should be able to combine this with davido's recommendation of Capture::Tiny to do the (re)capturing before the main script starts.

Update 2: No, it's unlikely. The Capture::Tiny documentation says:

Attempting to modify STDIN, STDOUT or STDERR during capture or tee is almost certainly going to cause problems. Don't do that.
