[m-dev.] And yet another, tuples of state variables.

Hi,

Another construction I tend to type way too often is:

   foldl(
     (pred(Elem::in,
           {!.Aku1, !.Aku2}::in,
           {!:Aku1, !:Aku2}::out) is det :- ..

which could be simplified to:

   foldl(
     (pred(Elem::in,
           {Aku1, Aku2}::!(in, out)
%       or possibly rather
           !{Aku1, Aku2}::!(in, out)

In other words, !{A, B}  would be considered equal to
       {!.A, !.B}, {!:A, !:B}

How does it sound to you?

Cheers, O.
