More questions on downwards binding,
for @foo - $a, $b { # two at a time
...
}
Interpretation #1:
for @foo[0..$foo:2] - $a,
@foo[1..$foo:2] - $b
{ ... }
Interpretation #2:
for @foo - $a { $b := $a; ... }
I like this second one, as a short-cut, but it's not worth
The when keyword can use a localizer that makes its target obvious but

given $x {
when /a/ { ... }
}
The problem is operations within the when-block that might expect to

when /a/ { s/a/A/; }
}
After all, I used a

when /a/ - {...}
when /b/ - {...}
...
}

Well, I like the idea of having Cwhen and the
