At one of my first jobs, I was tasked to rewrite a bunch of legacy Perl scripts in Python and the unless lines always made me trip up. I don't know why but it really messed with my mental flow when reading Perl code
It's nice. "if", "then", and "else". I spent a year programming a shitty roulette game on an Apple 2e back in high school. I still remember the joy of using if/then/else paired with goto to make a horrible mess of spaghetti logic.
Using a standalone 'else' would tickle my brain in the same nice way that being able to declare a variable inside an 'if' statement as if it were a 'for' loop (which you can do in modern C++) does.
I haven't written any Ruby for years, but I still praise it in every conversation I have regarding programming languages. It's basically a much simpler Python, with some design ideas that are both beautiful and deeply strange.
Ruby was designed to evoke joy and they absolutely succeeded. Usually, programming is mostly a means to an end to me. But using Ruby just feels so amazing, it's almost impossible to even describe to somebody who has never used it before.
