<function source-name>

[Alain Miniussi]

In the following rule, "function" is just a coemment:
 <unqualified-name> ::= <function source-name>
                       ::= <function source-name> <template-args>

But I think it's an incorrect comment, since <unqualified-name> 
can appears as the last component of a nested name and that a 
nested name can encode a class-enum-type.

Or maybe not ?
