Support named funs in the shell
The current code for the evaluation of ordinary funs is dependent
on the order on variables in the fun environment as returned by
erlang:fun_info(Fun, env).
To avoid the problem in the future, make sure that we only have one
free variable in the funs that we will need to inspect using
erlang:fun_info(Fun, env).
