What is $name for again?
It's the attribute name. This lets you have one initializer for
multiple
attributes. If my contrived example in tests wasn't so contrived
I'd say you
could use it and do this:
my %mult_for = (foo => 2, bar => 3);
my $multer = sub { $_[3]->($value * $mult_for{$_[2]} };
has foo => (initializer => $multer);
has bar => (initializer => $multer);
I am not strongly attached to passing that in.
I can see some use for it, but not that much. Perhaps it should be
($value, $callback, $attribute_meta_object) ? This would allow for
all sorts of advanced usage, but it could also be safely ignored by
those who dont want/need it.
