You use what is known as a lexical filehandle:

open my $fh, $file;

These are (slightly simplified) lexical variables that contain a reference
to an anonymous filehandle. The filehandle itself is still global.

Also search CPAN for the keyword "include". What comes up looks like
your problem has been dealt with before.
