Why recurse when you can iterate instead? :)

*gasp* .... thats not very functional! (I wont even bring up the fact you are using variable assignment, tssk tssk)

If we really want to be "efficient" about it, we would avoid the overhead of the wrapper subroutine, and just use straight perl's closures. 

sub compose {
    my (@funcs) = @_;
    return sub {
        my (@args) = @_;
        foreach my $func (@funcs) {
            @args = $func->(@args);
        }
        return @args;
    };
}

But really, that takes all the fun out of it ;-)
