- extern "C" is not required yet. C++ needs extern "C" because
it renames all the functions (name mangling) to some strange
names which describe the argument types. With extern "C", c++
is instructed to use function names as they are. lwc can already
call normal C functions. (maybe it would be useful for the
structure by value/reference case though...)

Namespaces. We do not have a 'scope operator' '::'. Should we
implement the scope operator for namespaces? If not what alternatives
could be used? Some examples. Would we implement the 'using' keyword?

Hacking lwc would require:

Add new keyword in norm.h and lex.c with ENTER_SYMBOL().
In the dcl.c parse the namespace in global_declaration.
(?local nested namespaces too heavyweight?).
Probably make a new namespace.c file to keep data, or
extend cdb.c to support namespaces.
