Re: subroutine ref while "strict refs"

[viffer]

I can probably put

if ($sub_routine =~ /check_char/} {
    check_char ($value1, $value2);
}

but is there a neater way? If someone else changes the record layout and adds a new subroutine, then the code would need to be changed to cater for it, which probably isn't ideal.

If anyone adds a subroutine, you will at least need a new 'use' statement to reference it. There does not seem to be much advantage in eliminating the need for other changes. Use a method that is clear and easy to modify. I like the dispatch table. Add a new entry for each new subroutine.

What?

I understood that the OP considered his symbolic references an advantage because a user could add new subroutines without modifying the original script. My point is that it is unlikely that this is possible. The additional effort to add a hard reference to a dispatch table is insignificant if you have to modify the script anyway.
