the first doesn't need to lookup dict which should make it a tiny bit faster
the second looks up dict in locals() and then globals() and the finds the builtin, so you can switch the behaviour by defining a loca...
Redefine tab as 4 spaces
.... In practice, you probably want your tab character width to be different from the width of your indents, in order to reduce the chance of tab characters masquerading as proper indents.
