hcchien raised the following question on #perl6[1]:
If I want to loop through a nine-element array three elements at a time, I do
my @a = 1..9;
for @a - $x, $y, $z { say $x }
But what if I don't care about the elements 1,4,7? Would the following
be a sane syntax?
my @a = 1..9;
for @a - undef,

Now for a related question: is it intended that ~$x and +$n be the same
as $x.as(Str) and $x.as(Num)? How locked in stone would this be, I.e.,
~ and + are macros that give the .as() form?
If I read everything correctly, this is the case.

If there's no (single) obvious interpretation of turn a value into a
number for a particular type, then don't struggle to come up with a
non-obvious one--I say just leave it undefined, or have it fail(), or
whatever.
Leaving it undefined is wrong

You wouldn't??! I certainly would.
Object references already stringify/numerify/boolify in Perl 5. Unfortunately,
they do so with problematic default behaviours, which is why Cuse overload
allows you to overload q{},

Excuse my noobness, I really have no idea about any of the inner workings,
but am just concerned with a more elegant syntax of doing it.
How about something like:
if ($condition) {
pre;
always { # maybe uncond instead of always, or both -- always could
# mean 'ignore all conditions' and uncond
Ingo Blechschmidt asked:
my $pair = (a = 42);
say ~$pair; # a\t42? a\t42\n? a 42?
Not yet specified but I believe it should be 42 (i.e. stringifies to value).
Note that S02 does specify that pairs *interpolate* to key-tab-val-newline,
so you can still get a\t42\n by writing $pair

I think separating stringification and interpolation leads to
unpredictability, and is a very bad thing.
