+If (i) `lhs` of type `Lhs` and `rhs` of type `Rhs` can be used in expression `lhs>=rhs`,
+and (ii) `Ret=dont_care` or the result of expression `lhs>=rhs` is convertible to `Ret`
+then inherits from __true_type,
+otherwise inherits from __false_type.
+
+The default behaviour (`Ret=dont_care`) is to not check for the return value of binary `operator>=`.
+If `Ret` is different from the default `dont_care` type, the return value is checked to be convertible to `Ret`.
+Convertible to `Ret` means that the return value of the operator can be used as argument to a function expecting `Ret`:
+``
+void f(Ret);
+Lhs lhs;
+Rhs rhs;
+f(lhs>=rhs); // is valid if has_greater_equal<Lhs, Rhs, Ret>::value==true
+``
+If `Ret=void`, the return type is checked to be exactly `void`.
