i know there are a lot of volunters,fans,developers who are very actively developing/improving the library but the main point of the argument(i think),is to realy focus on the stdlib improvements,not implying that the interpreter improvements are less important,just that the stdlib is currently lacking a bit in certain aspects already mentioned,to try to balance the ecosystem.
A more formal,focused,organized aproach to improve the stdlib is the point of the proposal,some sort of plan,roadmap is what is needed(in my opinion).
Some things that comes to mind and others based on feedback about the AFK non formal proposal are:
to refactor(someway) stdlib parts that are a bit inconsistent,as duplicated functionality of some modules,modules with just one function,obscure ways of working of some of them,to stablish realy strong naming,style coding conventions ie: modules names with get_type,getType,gettype.
To realy start a stdlib documentation effort,aspiring it to be the best,clearest documented stdlib out there.
To develop the greatest,more advanced library packaging system out there,taking the strengh and weaknesses of others(as CPAM) as a guide.
To start a planed and formal draft for py 3.0,some similar system as the iniciative from zope,the zope X3 project and maybe to #adelantar a litle python 3.0 realease(to jump from python 2.7 to python 3000 ^_^).
And many other great ideas to start making python the best language ever.
