But how would adding the directory of an importing module make any
difference?

Assuming non-hierarchical names, if the importing module is found, then
it's directory already must be in the seach path. So there is no reason
to add it.

Dropping all implicit directories but the current directory gets mine.
On the other hand, adding "." to the search path is no big trouble, and
then it will work exactly like java. A compiler could even allow search
paths to be tar-files (or tar.gz, tar.bz2, zip, jar, ...).
