that is a direct sub call and doesn't do any method lookup in the @ISA
tree.

that is irrelevant. if you don't use a method style call, you don't get
any OO semantics. so you have to have a blessed $self before you make
the call and you need to make a method call.
if Foo::gripe is written to take a class OR an object (and it could be
done that way), then you can call it like:
Foo->gripe( blah ) ;
or even Foo::Bar->gripe( blah ) ;
since you did he use base line earlier.
or even:
__PACKAGE__->gripe( blah ) ;
:)
but then you would need to use some default or package params to control
how it behaves vs what is normally passes in $self.

it isn't a problem in perl, but in your understanding of perl OO
semantics.
and now, how can i help you get your money into my account?
