i think you wanted to say 'as' after themselves. and returns should be
return (yes, english is wacky with plural nouns and verbs).
When in scalar context, aggregate variables such as C<@array>
and C<%hash> simply return themselves as Array and Hash objects
respectively.

Unlike in Perl 5, the notation C<&foo> merely returns the C<foo>
function as a Code object without calling it. You may call any
Code object with parentheses (which may, of course, contain
arguments). Whitespace is not allowed before the open
parenthesis, but there is a corresponding C<.()> operator, which
allows you to insert optional whitespace before the dot.

In numeric context, a Hash object returns the number of pairs
contained in the hash. A Hash in a boolean context returns true
if there are any pairs in the hash. In either case, any
intrinsic iterator would be reset. (If hashes do carry an
intrinsic iterator (as they do in Perl 5), there will be a
C<.reset> method on the hash object to reset the iterator
explicitly.)
is Hash the same as Hash object? i know %hash is both but is it ok to
change the name in mid paragraph like that??
just the usual minor cleanup of audrey's english. hell, she has to have
SOME flaws! :)
