I'll claim that when, like if, shouldn't need one. (I'd also normally
use multiple lines, but I'm trying to conserve newlines... :-)

Because two contexts (switch/case and CATCH) suggest that as "obvious"
behavior, and C<when> is targeted at those contexts. (CATCH is really a
variation of a switchish theme, but still...)
Example:
given $x % 3 {
when 0 { ... }
when 1 { ... }
when 2 { ... }
default { print "Surprise!\n"; }
}
for @A {
fragile();
CATCH {
when Exception::PEBKAC { ... }
when Exception::NotANumber { ... }
}
}
