Problem: Inconsistent naming of get_list_tv() and eval_dict().
Solution: Rename get_list_tv() to eval_list(). Similarly for eval_number(),
eval_string(), eval_lit_string() and a few others.
Problem: Using \{xxx} for encoding a modifier is not nice.
Solution: Use \<*xxx> instead, since it's the same as \<xxx> but producing a
different code.
