Newsfeeding isn't synchronous by itself. News reading is
even less deterministic :-)

Original version      1.640

Improved with slen[]  0.687

What however I find depressing is thinking that in so
many places the python runtime is wasting time looking
for something I'd never do (like replacing "len" or "str").
And for a function like the one the OP posted looks like
we're talking about more than 50% of the time being spent
doing those pointless searches.

It's IMO true that python is "fast enough" for most
situations... but ... what if I get sued from the
association for the rights of CPUs ? :-)

I didn't check python sources, is there a timestamping
for namespaces making it possible to cache lookups ?
Was this tried and didn't pay off ?


PS: Sorry if all this is hyper-naive...
