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.
