?- Z #= 0, Z #= X mod Y.
   Z = 0, clpz:(_A*Y#=X), clpz:(Y in inf.. -1\/1..sup) % Unexpected.

The expected result:
   Z = 0, clpz:(X mod Y#=0), clpz:(Y in inf.. -1\/1..sup).

8b7281fad0 ADDED: dif_si/2 
Source: https://stackoverflow.com/questions/20223390/prolog-a-person-is-a-sibling-of-himself

In Scryer Prolog, this is actually not needed, since Scryer Prolog provides
dif/2 in library(dif). However, it is still useful to provide dif_si/2 for two reasons:

  1) to more easily port code from systems where only dif_si/2 is available
  2) to provide correct disequality in other systems that adopt this library

8ab1155fc5 ENHANCED: use call_residue_vars/2 to show all pending constraints 
Example:

    ?- freeze(_, false).
       freeze:freeze(_A,false).

This was originally added in 04ba9bc11a,
then reverted, and is now restored.
