Description:
Hi.
It would be nice if next examples:
<< strictly left of int8range(1,10) << int8range(100,110) t
>> strictly right of int8range(50,60) >> int8range(20,30) t
&< does not extend to the right of int8range(1,20) &< int8range(18,20)
t
&> does not extend to the left of int8range(7,20) &> int8range(5,10) t
are extended by:
**not** strictly left of, **not** strictly right of, **extends** to the
right of, **extends** to the left of
Because without manual experiments I can not imagine the ranges that cause
'false' result for the examples above.
Thank you.
