% module resolution operator.
:- op(600, xfy, :).

% Implementation specific declarative operator used to implement
% call_with_inference_limit/3 and setup_call_cleanup/3. Compiler switches
% to the default trust_me, retry_me_else and some other instructions for all
% predicates that are marked with it. Indexing choice instructions are unchanged.
%
% Implementation details:
% Default instructions are not subject to inference counting, so their
% execution will not be considered if they happen to be called by
% call_with_inference_limit/3.
