Sometimes, you cannot avoid it. For example when generating a 1-1
binding to a library which uses methods named as Lua keywords. An
example of this is the Qt library - 19 of it's classes have a method
named 'end' [1], which you cannot call using Lua's syntax sugar. You
have to call it as follows:

    painter['end'](painter)

Does someone propose an elegant way to handle this? :)
