Yes, I think it should work with all builtins (and user functions as
well, basically anything where function("name") works).

Yes, thats exactly the way it would be used. It looks much nicer that
way and there is no need to escape "eval_expr" appropriately.

In my experiments on the weekend I made a simple wrapper class that
returned vim.bindeval("function('{0}')".format(attribute_name)).
I assumed that the FuncRef takes care of the appropriate
argument conversion when called (but I have not tested it extensively).
If it does, this should also be doable purely in python with the
exception of enumerating the available functions.
