"immediate"-function types allowed as the return type of functions. Example:

--------
void func(int a) { }
//typedef int ft(int);

typeof(func) test() {
}
----
Instead, the compiler complains that a return is needed (yet such return value
can not be specified). Using a typedef results in the same problem.

The following extended testcase crashes the compiler:

--------
void func(int a) { }

typeof(func) test() {
    if(true) throw new Exception("");
}
----
