ded4a75b9c use round brackets for meta_predicate declarations 
This is because meta_predicate is not a standard operator.

9e13f18463 ENHANCED: Domain error non_empty_list for empty arguments, addressing #1024. 
Example:

    ?- format("~d", []).

9d3f3eb013 ENHANCED: format_string domain error for invalid radix in format string 
This addresses #1024.

Example:

    ?- format("hello ~0r!", [12]).
    %@ caught: error(domain_error(format_string,"~0r"),format_//2)
 2021-08-14 20:04:07 +02:00

78c2f19e72 ENHANCED: If N is omitted in ~Nr or ~NR, it defaults to 8. 
This is for compatibility with Quintus, SICStus and GNU Prolog,
addressing #1024.

Example:

    ?- format("~r", [10]).
    %@ 12   true.

bf9654e138 ADDED: ... //0, describing an arbitrary number of elements 
This is a very versatile nonterminal. For instance, repeated elements:

    ?- phrase((...,[E],...,[E],...), "hello!!").
    %@    E = l
    %@ ;  E = !
    %@ ;  false.

066f740819 check for correct domain of integers in reifiable expressions also in the expanded code 
This is to preserve domain errors instead of failing silently. Example:

   ?- 5 #> 3 #<==> 2.
   %@ caught: error(domain_error(clpz_reifiable_expression,2),unknown(2)-1)
