&(fun, fun)
Agh, comma strikes again. It should be handled analogous to the ternary
expression. i.e. the expression above evaluates fun and then returns
the function pointer. The DIP now states this. (the second fun is in
address-taken position.) This is in agreement to how lvalue positions
propagate into comma expressions.
Adding more special cases are not gonna create a good DIP.
I don't they are so much a special case, as they are a clarification.
The two "exceptions" are simply explaining that because ternary operator
and comma operators evaluate to an lvalue, it is equivalent to putting the
& on the resulting lvalue.
