Why it has been translated to "char[0]" ?
For me "char*" would have been more appropriate.

It would be useful, for example, if I have a list of functions

This attempts to return a reference to the _variable_ `mc`, not a
reference to the class. Just remove `ref` from the function

Maybe we can lift this restriction if we know that the thread's
