Is Ruby such a good choice?
Let's see the Fibonacci implementation is C#, Ruby and Python. C#: Ruby: Python: As for me, C#'s Enumerable.Range() is somewhat messy compared to Ruby's and Python's variants. Ruby's optional parentheses around arguments seem just right, as well as 'return' keyword which now looks spare in C# and Python for me. Ruby's 40.times expression looks a bit weird, however, we could use more 'normal' loop like for i in 0..39. Python's absence of 'end' or '}' is the best thing in the whole language. I'm not joking. So, I can't judge at the moment whether Ruby or Python code is more expressive or readable. What about performance, C# wins with 9 secs, followed by Ruby with 1 minute and the Python variant took as much as 2 minute to execute. I must say that I don't bother about performance since in real life applications such numeric calculations encounter very rare and should not be done in dynamic scripting l
