Please don't dismiss optional typing without trying it first. Even if you don't add any type annotations yourself, you'll still benefit from the annotated libraries and from type inference. To get almost all of the tooling benefits, you only have to annotate arguments and the return value. That's it. Inside your functions you generally can omit them because there are enough types floating around. Literals have a type and if you call an annotated function, you also know what type you get back. E.g. this function is fully typed (none of the variables is purple): http://i.imgur.com/xHWlJVn.png http://i.imgur.com/xHWlJVn.png
