By analogy with Join, Meet(C1,C2) should return
a category which has the intersection of exports
of C1 and C2.
A simple test (see below) confirmed this semantics;
I also could not find a description of Meet in the guide.
aldor#include "aldor" define C1:Category == with { f: Integer; g: Integer; } define C2:Category == with { f: Integer; h: Integer; } D: Meet(C1,C2) == add { f: Integer == 1; -- OK; if this line is commented out, error: -- The domain is missing some exports. -- Missing f: AldorInteger }
