I'm interested in how builtins could be more efficient. I've read over some of the PEPs having to do with making global variables more efficient (search for "global"): http://www.python.org/doc/essays/pepparade.html But I think the problem can be simplified by focusing strictly on builtins.
Unfortunately, builtins can currently be shadowed in the module global namespace from outside the module (via constructs like "import mod; mod.str = my_str"). Unless/until that becomes illegal, focusing solely on builtins doesn't help - the difficulties lie in optimising builtin access while preserving the existing name shadowing semantics.
PEP 280 seems to be about as simple as an approach can get while still possessing the correct semantics.
Cheers, Nick.
