That's bad actually. We should find a coin telling "import all into
pyx namespace" or "leave it the way it is" ...

Well, thats why the idea is to allow for:

import pyx

pyx.text.set(...)

Note the missing "import pyx.text" statement. Importing something into
the pyx namespace should not make any difficulties in terms of name
clashs.

It might be also (indeed almost at least for PyX; I'm not familiar
with scipy) a question of creating a lot instances during loading. We
do have this problem with the attributes right now but an proposel
with a different approach is aborning. In terms of loading time this
should be the most crucial aspect.

Wasn't exactly this behaviour suggested? But then point 3 applies
always while it doesn't right now. (The automatic loading into the pyx
namespace is done at the import statement.)
