I guess the point is that you should leave the gotos to

Yes there is, in Perl 5.8. If you're using an older Perl, you can still get
Switch.pm from CPAN.

On the contrary, a goto is often most appropriate in expressing clear program
flow.

John,
Look up function dispatch tables on perlmonks.com.
It's a pretty good alternative to switch case statements (better than if-else,
anyway).
But as to your question, I don't know if there was any
functionality change made.

Much more gooder than the regex.
I doubt this.
Please provide an example.
