Oh, or it could be in version {} blocks. I like that.
I think we should actually whip up a working model. It needn't be a
compiler feature at this point - we can use pragma(msg, "BUILD: " ~
param) for now and have a helper program scan dmd's output.
+1, sounds fun. :)
Rather than pragma(msg), you could also use pragma(liburl), and run dmd
with "-ignore -v". You can parse the pragma from there. (I think you'd
need to write `pragma(liburl, "name-in-quotes", "url-in-quotes")`, a
slight diversion from Andrei's syntax, but otherwise it would work.)

I just realized that one advantage of the download being integrated in
the compiler is that the compiler is the sole tool with full knowledge
and control of what modules are imported. A tool could repeatedly run
the compiler with -v and see what modules it couldn't load, to then
download them. (Also, of course, a tool could rely on extralinguistic
library management control that has its own advantages and disadvantages
as we discussed.)
