Postings from September 2005
In a private conversation with Larry this afternoon, he said that by
default "$foo" and ~$foo and $foo.as(Str) all give the same result
(assuming scalar context, etc.). And that "@foo[]" and ~@foo and
@foo.as(Str) are the same as join(' ', @foo) where join is effectively:
sub join(Str $x is rw, @A) {
my Str $y = '';
for $z -> (@A) {
$y ~= ~$z;
} continue {
$y ~= $x:
}
return $y;
}
Also that a pair ($x => $y) stringifies to "$x\t$y" and that ~@A for an
array of pairs is the same as join("\n", @A);
It is also intended that .as(Str, ...) takes extra named args (names
TDB) for things like separators and sprintf like format strings so you
can customize it, including ways to change the defaults for a class
(like the separator for arrays of pairs being "\n" instead of ' ').
