Where does the convention "at-at-slash" come from?

[rstuven]

As in @@transducer/init, for example. Just out of curiosity.

I've recently seen this convention used in other libraries (eg. here and here), but I saw it here first. I suppose it's a way of namespacing, but I couldn't find an explanation or explicit mention about it anywhere.

Thanks.

Probably from urls? Also Clojure keywords are like this so probably my bias.

@rstuven It comes from the ES2015 spec (previously ES6 draft) referenced in #20 which @swannodette coordinated.
