=head1 NAME
Memoize::AnyDBM_File - glue to provide EXISTS for AnyDBM_File for Storable use
=head1 DESCRIPTION
This class does the same thing as L<AnyDBM_File>, except that instead of
L<NDBM_File> itself it loads L<Memoize::NDBM_File> if L<NDBM_File> lacks
L<EXISTS|perltie/C<EXISTS>> support.
Code which requires perl 5.37.3 or newer should simply use L<AnyBDM_File> directly.
