okay but we still have the hiding issue, in case we want it to
work with arbitrary hashes as well as defined structures: a neat
trick if we can do it, and we can. In that case, the hiding properties
are not just one more thing to keep track of but become a
security issue analougous to having . early in yout $PATH variable.
Therefore a way to indicate "this is near the end of a record name"
is required. Dot already means too much (although is it defined
between barewords? It might work, it works elsewhere) so I used \
in the way of the directory indicator from DOS, and in an allusion
to unary \ as the reference-of operator.
And you dont have to make sure the $s on the left of the names match
the {}s on the right, just use one $ and string the names together with
backslashes. This is not easier?
$one{two} is $one\two
$$one{two}{three} is $one\two\three
$$$one{two}{three}{four} is $one\two\three\four
If we have _that_ already,
with %one\two {
push @\three\four, 5,6;
}
is clear and invulnerable.
