Re: Sprinting at PyCon

Hi Alain,

another unique feature of Stackless is pickling/unpickling of tasklets 
and many other python types. This feature is essential for many 
applications and probably needs some additional C-code besides 'tealet' 
/ '_continuation'. That said I like your proposal, but I doubt that we 
have enough man power to implement it.

Cheers
   Anselm
