comment RegionIntersection: Point or Line?
Technically, I suppose, a line with no length may be equivalent to a point. However, I would expect Mathematica to return it in its standard form. In the particular case I am working on, I am trying to count the number of times a line crosses another line. Of course there is a workaround, but it is a bit clumsy.

comment RegionIntersection: Point or Line?
Yes, I've used RegionIntersection in many other cases in which it returns a combination of Points and Lines

comment How to generate and draw simple bipartite graphs?
@Athanassios, It works for me with no problems. But I am using version 10. What version are you using?

comment How can I define operators that have the behavior I want?
Doesn't Mathematica automatically simplify logic expressions? In this case Union[Intersection[a,b],b] should be automatically be simplified to b if a, b are sets. By the way, = is the assignment operator, Set; Equal is ==.

revised Converting imported data into a list of pairs
Clarified that "it" refers to the string, not to the list.

+1 Nothing fancy. Nice and clean.

comment Boolean value of proposition assuming previous boolean values of parts of the proposition
Patrick, Why don't you post your comment as a response? I wasn't aware that Simplify could make boolean inferences.
