LWP::MemberMixin - Member access mixin class

SYNOPSIS

        package Foo;
        require LWP::MemberMixin;
        @ISA=qw(LWP::MemberMixin);

DESCRIPTION

       A mixin class to get methods that provide easy access to
       member variables in the %$self.  Ideally there should be
       better Perl langauge support for this.

       There is only one method provided:

       _elem($elem [, $val])
           Internal method to get/set the value of member
           variable $elem. If $val is defined it is used as the
           new value for the member variable.  If it is undefined
           the current value is not touched. In both cases the
           previous value of the member variable is returned.
