Hmm... I used to be quite the fan of Python, yet not long ago I met
Ruby and fell in love almost instantly. Some of the features I like the
most:

- statement modifiers:

< "return a if a.value == true"
< "database.query(q) unless database.connect == error
(etc)

- unless as "if not", since it gives nicer code to read

< unless false then print 1 # this prints 1 forever

- iterators, such as times (already mentioned)

- 'case'

< case var

Yeah, yeah, I know that :-)
What I mean is that most of the time I find the code more "readable" (I
know that more readable code ain't better code, but it helps when you
work with other people...).

My mistake :-S
The comment in the code was erroneous, I shouldn't write messages to
the list while asleep ^_^

'unless' works as 'if not', not as 'while not'. Sorry for that :-)

Anyway, it does improve readability. I know that it doesn't necessarily
makes code better, but it's a nice "trick" that I like :-)

Other nice thing about ruby is declaring regexps as /regexp/ rather
than having to re.compile("regexp"), and having a built-in operator to
match against them (of course, as everything in ruby, overloadable in
each class :-))
