Recently, I learned that Ruby developer Matz is developing a programming language called Streem. Streem is a language specialized for stream processing. I think people like sed and awk will like this language. I like stream processing, so I hope that this language will popular.
streem sample program(FizzBuzz)
seq(100) | {x -> if x % 15 == 0 { "FizzBuzz" } else if x % 3 == 0 { "Fizz" } else if x % 5 == 0 { "Buzz" } else { x } } | stdout
