This is expensive and dangerous: 
eval "require $class;"; # Note: "" *NOT* {} !

whereas this is cheaper and safer (no firing up of the compiler): 
(my $file = $class) =~ s#/#::#g;
require $file;

Please note that for future programs. (Yes, portabilty to macs and VMS is sacrificed.. for that, pull down File::Spec. But this works on Unix and Windows.)

    Don't you mean something like this instead?
    (my $file = $class) =~ s^::^/^g;
require "$file.pm";

    Now, this seems to work using file spec:
    my $file = File::Spec->catfile( split /::/, $class ) . ".pm";

    Thanks for the time and tips,
