I tend to declare vars with their context. Especially in functions that are (unfortunately) longer than usual, having all vars at the top makes for a mess. But

I tend to declare vars with their context. Especially in functions that are (unfortunately) longer than usual, having all vars at the top makes for a mess. But I don't think the `let` syntax is going to be a problem for people who write plain JavaScript. It's more likely to it might become a problem for languages that compile to JavaScript. (For example, soak operators in CoffeeScript.)
