digitalmars.D.learn - Problem with trying sample from doc page

Hi! I've been experimenting with D functions, and found this 
piece of code:

//
int abc(int delegate(long i));
int def(int function(long s));

void test() {
   int b = 3;
   abc( (long c) { return 6 + b; } );  // inferred to delegate
   def( (long c) { return c * 2; } );  // inferred to function
}
//

On linux machine with [DMD64 D Compiler v2.065] it doesn't 
compile, giving me this error:

test.d(10): Error: function test.def (int function(long s)) is 
not callable using argument types (long function(long c) pure 
nothrow  safe)

Here DMD infers  (long c) { return c * 2; }  as   long 
function(long c).
And "def" definition doesn't match.
Is that an error in the docs, or mayber I'm doing something wrong?

I would just change all the longs to ints and it would probably 
work. Or all the longs to ints.

It really should have been consistent in the docs, since the 
point of this is delegate vs function, not int vs long...
