in reply to callback or call now?

I think that you've got it turned around. The common case, in my mind, would be import by ref instead of import by callback. The second slash means "Something a little funny is going on" which would be the callback case, to my mind.

    If backslash simply means "not the default", then its meaning varies with your expectations.

    I'm thinking that it more-specifically means "take it literally, not as instructions to find the answer.". Then you get this progression:

    foo => &bar means call bar now when the structure is being built. foo => \&bar means call bar later, when foo is imported (and bar can see the context of what the impoter is asking for). Finally, foo => \\&bar will call bar even later, when foo is actually called after being imported.

[Corion]: I'm interested in how their product actually works. It uses websockets between two non-browser components, so there are some weird technology decisions, or rather, I assume the product started out as something completely different :)
