This is taken from the Ruby Koans. It’s the shovel operator, and it appends stuff to a string.
original_string = "Hello, " hi = original_string there = "World" hi << there
So I'm totally down with the idea that hi now equals "Hello, World". No problem. But in fact, original_string also now equals "Hello, World". That is totally messed up! :)
But seriously. What is up with that? is there way to not find this just... just... shocking?!
