If it's going to stay "imp" (which I initially found confusing; How about "Import"?), "the imp idiom" might do but imps have a very insignificant appearance in Harry Potter. (There are "Pepper Imps sold at Honeydukes in Hogsmeade".)

That's obviously a self important lookup.

I haven't followed DIP 1005 closely. Has there been any discussion of automatic imports that seems to have potential to make both the user's and implementor's lives easier:

void foo(std.datetime.Duration dur) {
    // ...
}

Can the compiler automatically import std.datetime for both the implementation above and the user? Or, too much beer at work on this Friday? :o)

How does the compiler know that "std" is supposed to be an import rather than a misspelling of a previously declared "stc" ?

But they have much significance in Doom :)

...part of which takes place on Phobos ;)

 Yes, all except of good IDE and tooling.

... because of string mixins.

please refrain from insulting string-mixins.
they are by far the most understandable of meta-programming facilities.

 std.datetime exists.
 I think, allowing fully qualified names and automatic importing of used fully qualified names will be much, much better, than introduction of string mixins literally everywhere.

 Most understandable don't mean "good to use". We can do many things with it but it's really hack and easy way to obscure code and prevent any automatic analysis of it. Because when we have string mixin in code - any tool should become a compiler to work with it. So my opinion: they must be avoided as much as possible.
