I have been wondering, is there a no-op in Ruby? Then you could do like in
Python:
while 1: pass

Cool, thanks.
I've just realized you don't even need the 'nil' to flesh out some
syntactically valid functions/methods/case statements that do nothing:
irb(main):005:0> def foobar
irb(main):006:1> end
=> nil
irb(main):010:0> x = 1
irb(main):011:0> if x == 2
irb(main):012:1> puts "Two!"
irb(main):013:1> elsif x == 1 # do nothing
irb(main):014:1> else
irb(main):015:1* puts "Not 1 or 2"
irb(main):016:1> end
=> nil
technically they return nil but that is incidental...

nil while true
while true; end
...wait. Why are we doing this? And why are we disallowed from using loop{}? Okay, here's another:
alias repeat loop; repeat{}
Or:
(1..1.0/0)..each{}
How about:
callcc{|$cc|};$cc
Shall I continue, Anil?

Golfing slightly and not very interestingly:
0while 0
(that's not a syntax error, oddly)

Heres another one:
(a = lambda { a.call }).call
Of course this is one infinite loop that will probably terminate.

Err... okay, I can think of another:
raise rescue retry
Wow... that one's pretty elegant. This one much less so:
1.times { redo }
I'm out... maybe something cute with threads, or throw/catch, or ensure?
Is there a reason for your question? Just a ruby-talk game?

nil while 1 && 1.times {redo} && raise rescue retry
