Hi,
I don't want to be inpolite but what if fun returns a delegate which
accepts a delegate and fun is overloaded (the delegate parameter is
optional):
void delegate(void delegate()) fun();
void delegate(void delegate()) fun(void delegate());
...
fun(){...} //does this result in void or void delegate(void delegate())
...
It's the same as with property if they are allowed to call with parens.
But this is a very unlikely to happen. I don't even know if delegate are
allowed to take delegate as parameters.
