in thread Capturing all (and I mean all) output to a file

I guess IO::Tee objects aren't interpreted as filehandles...? I'm a complete newbie to module coding/OO Perl, so I have no idea why it's looking for an object method rather than using the builtin fileno() function...

Can't locate object method "FILENO" via package "IO::Tee" (perhaps you forgot to load "IO::Tee"?)
