That would make a lot of sense if it is what Ruby actually did, but
unfortunately the actual roles of ... and .. are reversed from what
you just said.

E.g. from here:
http://www.techotopia.com/index.php/Ruby_Ranges
"""
  1..10    # Creates a range from 1 to 10 inclusive
  1...10   # Creates a range from 1 to 9
"""

And it's also true that it's probably too easy to overlook the difference.
