 jiti_suggest_modes is det
 jiti_suggest_modes(:Spec) is det
Propose modes for the predicates referenced by Spec. This utility may be executed after a clean load of your program and after running the program. It searches for static predicates that have been called and (thus) have been examined for candidate indexes. If candidate indexes have not been materialized this implies that the predicate was never called with a nonvar value for the corresponding argument. Adding a mode/1 declaration may be used to inform the system thereof. The system will never examine arguments for indexing that have been declared as mode -.

Note: This predicate merely detects that some predicate is never called with instantiated specific arguments during this run. The user should verify whether the suggested - arguments are correct and typically complete the mode by changing ? into + (or -) where applicable. Currently, in SWI-Prolog, mode/1 declarations have no effect on the semantics of the code. In particular, a predicate that declares some argument as - may be called with this argument instantiated. This may change in the future.

Arguments:
Spec- uses the same conventions as jiti_list/1.
