Hmm... instantanously the security alarm bell sounds.

Yuk. I don't really like this approach, why not consider
HTML::Template which you can get from www.cpan.org - this
is a HTML templating system that can do most of this work...
in a way that someone coming along later can maintain easily.
Alternatively, use server side includes (SSI) which
basically does the same thing. I can't understand the
advantage of structuring things like this.

Warning! That file would be security critical, and should be
treated with great care. Anyone in control of it could call
arbitary perl functions and subroutines - albeit without any
arguments.
You need:
{
no strict;
&{$var};
}
Did I mention all CGI scripts should start rather like:
#!/usr/bin/perl -wT
# warnings_/ \_Taint mode checking (EXTREMELY IMPORTANT WITH CGI)
use 5.005; # Minimum version
use strict; # Strictures - VERY important
Take care,
