> It's crazy that in these slides he says "I wanted a hipster language" -- most languages use [] for arrays so I used (). WHY!!!!? Just to be different? No actual real advantage? That's a terrible reason and a great way to make it hard for new people to adopt your language.

Parentheses for array and map access really bugged me until I grokked functors. They're really all doing the same thing, and the mathematical symmetry of using the same syntax for all of them is very pleasing.
