Definitely by design.

Have a look at PEP 328 - http://www.python.org/dev/peps/pep-0328/

"In Python 2.4 and earlier, if you're reading a module located inside a 
package, it is not clear whether
import foo
refers to a top-level module or to another module inside the package. As 
Python's library expands, more and more existing package internal modules 
suddenly shadow standard library modules by accident. It's a particularly 
difficult problem inside packages because there's no way to specify which 
module is meant. To resolve the ambiguity, it is proposed that foo will 
always be a module or package reachable from sys.path. This is called an 
absolute import."
