I think it is. There should be different syntax to import from
"standard" places and from "current directory". Similar to the
difference between "foo.h" and <foo.h> in cpp.

Searching the current directory by default is the problem.
Nobody in their right mind has "." in the shell PATH and IMO it
shouldn't be in Python's import path either. Even those
wreckless souls who do put "." in their path put it at the end
so they don't accidentally override system commands.
