"HANDLE" there means "Windows HANDLE thing", a pointer.
If you say so. A "handle" can be various things in a computer
program: sometimes it's a pointer, sometimes it's not. But "infinity"
is not a sensible name for a pointer. It's reasonable to assume that
it isn't one.

I don't know beans about Ruby or have any preconceived ideas about it. I have noticed, however, that every programmer I talk to who's aware of Python is also talking about Ruby. So it seems that Ruby has the potential to compete with and displace Python. I'm curious on what basis it...

I think everyone who used Python will agree that its syntax is the best thing going for it. It is very readable and easy for everyone to learn. But, Python does not a have very good macro capabilities, unfortunately. I'd like to know if it may be possible to add a powerful macro system to Python, while keeping its amazing syntax, and if it could be possible to add Pythonistic syntax to Lisp or Scheme, while keeping all of the...
