=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.
