Ah, okay, I guess I used the wrong word. While {} treats barewords as
quoted strings, it doesn't treat whitespace as quoted. Therefore, in
the Perl 6 example referred to:
$x{a }{b } = 1;
$xxx{aaa}{bbb} = 2;
print $x{a }{b }, "\n";
print $xxx{aaa}{bbb}, "\n";
$x{a }{b } should be equivalent to $x{"a"}{"b"}, but not equivalent
to $x{"a "}{"b "}. Thus, the above would be a compromise keeping
columns lined up but not allowing whitespace immediately before "{".
At least, I think that's how it'll work. I learn best by trying, rather
than just reading, so I may not have a complete handle on how things
will be changing for Perl 6.
