I know it used to be that way back near the Dawn of Time, but methods
don't automatically topicalize anymore unless you explicitly name
one of the parameters '$_':
method test ($_: $value) {
setup();
when $value { doit() } #[smart-match the calling object $_ against
$value.]
}

: qualify as an abnormal termination of the method?)
Well, according to S04:
"If the smart match succeeds, C<when>'s associated block is
executed, and the innermost surrounding block that has C<$_>
as one of its formal parameters (either explicit or implicit)
is automatically broken out of."
So it merely returns normally from the method, which is what you'd
generally expect. If you have more questions about switches, S04
probably already discusses it.
