[Python-Dev] PEP 340 -- loose ends

I'm not quite sure why, but there seem to be a 
workaround (forseen in PEP 340). And people seem
to be "using" this already <0.5 wink>:

 [Alex Martelli]:
 > for name in filenames:
 >      opening(name) as f:
 >          if f.read(2) == 0xFEB0: break

Moreover, an anonymous block should have
no <<name>> (neither 'block', 'with', 'using')
to be true anonymous <1.0-Tim-Peter'ly wink>

cheers,
Senra
