Allow me to clarify.
C has for, while, and do-while. That’s it.
Ruby has for, while, do-while, until, rescue, inlined conditionals, optionals, and iterators, for what amounts to the same task; not to mention exceptions (something the C standard has repeated swerved away from, wisely) and lambdas.
I’m not saying that there isn’t a time for Ruby, but if you think C falls into the same category then we’re very much in disagreement.
