Ah yes, one of the many languages where designers were like "you know what sucks about writing code? All that damn punctuation you write! It takes so long to type those curly braces. We're going to make a language where all our punctuation is invisible! Our code will be so much cleaner when all these important control-flow and context-determining marks are unable to be seen anymore!"

Looking at you, Python, YAML, and Coffeescript.
