NAME
    Memoize::AnyDBM_File - glue to provide EXISTS for AnyDBM_File for Storable use

DESCRIPTION
    This class does the same thing as AnyDBM_File, except that instead of NDBM_File itself it loads
    Memoize::NDBM_File if NDBM_File lacks EXISTS support.

    Code which requires perl 5.37.3 or newer should simply use AnyBDM_File directly.
