You won't be able to query attributes at run-time? Even within
the class? I rather like the ability to loop through
the attributes of an object with something like this Perl5 code:
foreach my $attr (qw(foo bar baz))
{
print "$attr: $this->{$attr}\n";
}
You will. But they won't be entries of a hash. They'll be
separate variables and associated accessor methods.
So maybe something like this:
foreach my $attr (qw(foo bar baz))
{
print "$attr: $self.$attr()\n";
}
