The thing is that a “SymbolTable” is a “iplist” (it inherit from it) and, iplist has a “sort()” method, it is not clear why we can’t sort then?

The fact that SymbolTable implementation is breaking one of its public method does not seem right to me.

Also, in general, the design assuming any instance of a SymbolTable<GlobalVariabl> is owned by a Module and inspecting the “parent” using magic trick, seems … broken.
