int fun(int x);
pragma(msg, typeof(fun).stringof); // int(int x)
alias funType = int(int x);
static assert(is(funType == typeof(fun)));

pragma(msg, typeof(&fun).stringof);

prints:

int delegate(int x)

I was expecting:

int function(int x)

If fun is nested it will be a delegate. Only if top-level or 
static will it be function.
