% Test case for solutions
|
|
%
|
|
% Author: trd
|
|
%
|
|
% This test case exercises a number of features:
|
|
% - The ability to modecheck equivalence insts correctly (the
|
|
% Mercury compiler of Jan 20 1997 couldn't compile code like
|
|
% this - in fact if you made mypred == ground it still couldn't
|
|
% get it right).
|
|
% - Solutions of higher order predicates
|
|
% - In non-conservative GC grades, deep_copy of closures (since
|
|
% solutions is implemented using deep copy on them).
|
|
% - Higher order syntax -- P(5, 1, X)
