I am trying to use list constructor in SWI-Prolog, but am getting 'dict' expected error.
For example,
.(a, []) == [a].
ERROR: Type error: `dict' expected, found `a' (an atom)
ERROR: In:
ERROR: [11] throw(error(type_error(dict,a),_14808))
ERROR: [10] '$type_error'(dict,a) at /Applications/SWI-Prolog.app/Contents/swipl/boot/init.pl:3369
ERROR: [9] '$dicts':'.'(a,[],_14874) at /Applications/SWI-Prolog.app/Contents/swipl/boot/dicts.pl:46
ERROR: [8] '<meta-call>'(user:(...,...)) <foreign>
ERROR: [7] <user>
Exception: (9) '.'(a, [], _14200) ?
Could anyone help me configure this functionality?
