Er, no. That just ties the variable $x to class foo, presuming there
is a class foo. Doesn't say anything at all about the *contents* of
$x. You can type the value of $x by saying:
my foo $x;
but that still doesn't create an instance.
Constructors haven't been designed yet, but one approach would be to
have the built-in opaque object type assume a constructor name of "new"
if you don't declare one. I can see some problems with that though.
Certainly the Perl 5 way of creating instances will continue to be
supported--that is, with the data structure totally orthogonal to the
class binding. Whether the new opaque objects are constructed inside
or outside of C<bless> is still to be decided.
