Which mainstream programming language has the ugliest syntax?

Regardless of the language's usefulness, which language fails the beauty contest the worst?

Objective-C and Python

I was literally searching on Google “Why Ruby is so ugly?” when this article appeared on the list. “puts” in Brazilian Portuguese is a slang for “oh, fuck!”, or when something was messed up. And when I saw a code example with:

say = ‘hello’
5.times { puts say }

I only could think what kind of psychopathy is that.

Definitely python. Oldschool 80's-style. I wonder how this could become so popular.

Any language that uses ":=" for assignment - GO and Pascal comes to mind, and any language that uses tabs or spaces to define scope in the code - Python, Spin and make come to mind.

I'm of the opinion that most (if not all) language syntax looks pretty anyways, as soon as you view the code with a cool IDE, with pretty font and theme. Also formatted by a code formatter.

Swift is ugliest, look at this AppDelegate method for example...

override func application(_ sender: NSApplication, delegateHandlesKey key: String) -> Bool {
    return key == "tasks"
  }

CoffeeScript by far, its horrid, I rather write brainfuck than Coffee!

Rust. It is forcing me to consider allowing semicolons in my JavaScript.
F# would never do such a thing!

This discussion is really unfair for JS developers :)

assembly language

I know java and ruby only so I do not have much to say about other languages. Java is definitely verbose but I don't see it as ugly. ruby is build to write elegant code but I find it a bit of awkward and insecure because of its simplicity.
