I don't consider this much of a problem.  If you want to use module that pollutes
the namespace a lot with rarely called functions that have short, common names,
that's what static or local (i.e. within a function/class/struct, which only can
be done since the last release of DMD) imports are for.  It's a problem in other
languages, but in D there are elegant solutions.

As an example, before I knew about static imports and before we had local imports,
std.file's propensity to collide with just about everything due to its use of
short, common names drove me crazy.  Now, I really don't mind because I always
import it either statically or locally.
