Silly function call lookup stuff?

Dear pythonians,

I've been reading/thinking about the famous function call speedup 
trick where you use a function in the local context to represent 
a "remoter" function to speed up the 'function lookup'.

"This is especially usefull in a loop where you call the function a 
zillion time" they say.

I think this is very odd behavior. 

Why isn't the result of the first function-lookup cached so that following
function calls don't need to do the function-lookup at all?

And if the context changes (an import-statement say) reset the
cached 'function-lookups'.

This way any function would only need to be looked up once.
