How to mark anonymous entities as implementation defined

[mizvekov]

For a test case such as:

extern struct { int a; }
  /// A test variable named 'y'
  y;

How to mark the unnamed class as implementation defined?
Right now, this requires adding an entry to the configuration with the name of the class.

We could either:

• Give the class a legible name and make this work with that.
• Support some kind of marker attached to the class, such as: /// implementation-defined
• Require the user to provide a name in this case.

The legible name is probably not workable, because the user can't know in advance what the name will be. And the name could change. Naming symbols explicitly in the config file is a poor solution. It is better to use a namespace for that such as implementation_defined. That has its own problems though. No perfect answers in sight.

Yeah, it looks to me like this would be the best solution:

/// implementation-defined
extern struct { int a; }
  /// A test variable named 'y'
  y;
