I like it, but idiomatic symbols are tough. When I look at some functional languages they seem so dense with operators that I have to use some inference (which I probably get at least partially wrong) to glean the meaning. This is a good operator that, in my opinion, should be in a dynamically-typed object-oriented language. But it is not as universally understood as most of JavaScript.

There is a place for languages that use more keywords and fewer operators as a design choice. Of course there also need to be languages that don’t have the undefined/null value and don’t need this.
