Interesting that you mentioned it. Doesn't Ruby handle it this way?

Let's see how this would look like in Python:


def distance of point1, point2:
     # Pythagoras

point1 = (3, 1)
point2 = (1, 4)
print distance of point1, point2


Hmmm. Although I like the lightness of this, it's somewhat confusing, isn't?


Best,
Sven
