I think you're mistaking syntactic noise with semantic information. Writing the
module name *does* have semantic information, even when you can find it too
verbose. It's not the same to use, for example, path.join() than string.join(),
the module carries semantic information. Of course you can name the functions
path_join() and string_join(), but that kind of defeat the point of a module

I don't think a language should depend on a good IDE, if you take that too far
you end up with Java. I really think the "the IDE should do that" is the worse
argument ever. I don't even use a IDE (not because there is no good IDE for D,
I just don't use IDEs for any languages). But this is besides the point,
because this discussion is just about personal preferences.

read the code and track dependencies.

But I don't know where that sort came from. I'm missing important information
(when reading a program). You either have very long and descriptive function
names, or you use the module system properly. I agree that when you use a
symbol a lot is desirable to have it imported in the main namespace, but in
that case you can always use selective imports. With selective imports you get
the less typing for things you use a lot *plus* you can know where every symbol
And again, we are only talking about changing the *default*, you can always use
import * if you want to.
