There’s a lot of features of Ruby that I like, but there are some that just drive me nuts like blocks not taking blocks and the ampersand operator. Raganwald did a great job of explaining blocks, procs, and the ampersand in this blog post: Explanation of Ruby’s Unary operator. I came away with the feeling, “Wow! It took that much explanation just to tell how to send blocks around?” If blocks were first-class citizens, Ruby would be more elegant.
