upper and lower bounded constraints are not working #24

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Constraints of the form 2 <= x1 <= 4 or 2 <= (x1+x2) <= 4 are not functioning 
properly.  This is because Python instantiates the middle part as an expression 
twice instead of using the returned value from the first <= evaluation for the 
second.

Actually, Python's evaluation rules haven't changed, so something must be 
triggering the second instantiation.  See
