&gt; I&#x27;ve never used a language with a better standard library.<p>I found myself wishing that it would take more from Scala&#x27;s example, especially the collections, where they could certainly use some more utility. I also wish they&#x27;d do more to support a more functional style of programming; little things like, say, turning `if` into an expression, which, while I don&#x27;t think it would affect existing code at all (the result would just be thrown away), would allow you to assign to a constant value, avoiding undefineds altogether.
