in reply to Re^3: Using Exporter module
in thread Using Exporter module

I think we can acheive this by creating private method. and not call like $self->_method() Inside module
if we call the private method like this: _method($self,arguments.) and if we try to call this subroutine outside then this will thorw an error.
