    =over 4
    =item new($issn)
    The constructor accepts a scalar representing the ISSN.
    The string representing the ISSN may contain characters
    other than [0-9xX], although these will be removed in the
    internal representation.  The resulting string must look
    like an ISSN - the first seven characters must be digits and
    the eighth character must be a digit, 'x', or 'X'.
    The string passed as the ISSN need not be a valid ISSN as
    long as it superficially looks like one.  This allows one to
    use the `fix_checksum' method.
    One should check the validity of the ISSN with `is_valid()'
    rather than relying on the return value of the constructor.
    If all one wants to do is check the validity of an ISSN,
    one can skip the object-oriented  interface and use the
    c<is_valid_checksum()> function which is exportable on demand.
    If the constructor decides it can't create an object, it
    returns undef.  It may do this if the string passed as the
    ISSN can't be munged to the internal format.
    =item $obj->checksum
    Return the ISSN checksum.
    =item $obj->as_string
    Return the ISSN as a string.
    A terminating 'x' is changed to 'X'.
    =item  $obj->is_valid
    Returns 1 if the checksum is valid.
    Returns 0 if the ISSN does not pass the checksum test.
    The constructor accepts invalid ISSN's so that
    they might be fixed with `fix_checksum'.
    =item  $obj->fix_checksum
    Replace the eighth character with the checksum the
    corresponds to the previous seven digits.  This does not
    guarantee that the ISSN corresponds to the product one
    thinks it does, or that the ISSN corresponds to any product
    at all.  It only produces a string that passes the checksum
    routine.  If the ISSN passed to the constructor was invalid,
    the error might have been in any of the other nine positions.
