The C switch will evaluate the expression (once),
and jump to a case that matches the expr. The case
usually ends in a break, but it doesn't have to. Other
case statements can be sprinkled in the code block.
The break is almost always there. So I used it in
my example.
Okay, sometimes it isn't there, and you get
lovely features like the phone system crash
of 1991-01-15.
What's the Perl alternative to that behavior?
You haven't offered one. 'last' is Perl's 'break'.
