This module extends the support for association lists in the SWI-Prolog standard library.

 merge_assoc(+New:assoc, +Old:assoc, -Merge:assoc) is det

Merges two association lists (New and Old) into one new association list (Merge).

If the same key appear in both New and Old, then the value from New is used and the value from Old is discarded.

 transpose_assoc(+Original:assoc, -Transposed:assoc) is det

Transposes an association list, i.e., turns all keys into values and all values into keys.
