We can say Good-Bye my sweet Perl 4 anytime?

fml-support: 07849

Q: We have no more power to support fml runs under both perl4 and
   perl5. Especially it is worse for patch contributors.

A: Yes, I think so.

Like Larry said, we need not to rewrite fml 4.0 to perl 5 module style
since the current fml 4.0 and 4.0.x works well.

Precisely speaking, fml after 4.0 allows perl 5.0 module style and
perl 4.0 old fashions too.
