That's ridiculous! You have many things in glib (like ghash, gstring
etc.) which can be done better with specific language constructs in
some languages (associative arrays, operators on strings etc.). Yet,
as glib is primarily foused on C, it's a good idea to implement those
features, which are (in plain C) missing...
