%
% Explicit module qualification operator. True if T succeeds when called in the context of module M.
% This calling context determines how predicates resolve to user-defined procedures.
% The context is flat. That is, in the goal `M2:M1:T`, predicate lookups are performed only in M1 and not M2.
%
% Consider carefully before using explicit module qualification.
% Prefer meta-predicate declarations when possible.
