Because at the time i made this statement we were discussing 100% true OOP (you know, the kind of paradigm where object definition identifiers start with a capital letter? *estoeric-wink*), but more importantly because i don't find the current implementation of array and list to be consistent.

Well since /all/ objects will have help available it should be defined Object#help and then propagate downwards. But even true OOP languages need a few global functions... *gasp*... oh yes! A few that come to mind include:

 globals, locals, vars, compile, eval, exec, input, print, dir
 
And don't forget, we still have module namespace to deal with!
