You can inject at compile time unless you can only determine what to inject
at runtime.  Like locales, automated testing engines, themes.

There are use cases for both.  A good DI implementation will support both.
I have a further goal that compile-time DI would be "legal ActionScript" in
that you could output the AS that is going to run. (Sort of like the
-keep-generated-actionscript option today).  That would make it a whole lot
easier to debug.
