 Interesting thread. I've been working on a hand-written D

 you mentioned above. In same cases it's actually not clear, or 
 downright wrong what the grammar spec says. For example, here's 
 one off of my notes:

   void func(int foo() { } );

 The spec says that is parsable (basically a function 
 declaration in the parameter list), which makes no sense, and 
 DMD doesn't accept.

I'm wondering about the statement above, over in digitalmars.D
thread, that the declaration makes no sense.

http://dlang.org/expression.html#FunctionLiteral has
void foo(int function(int) fp);

Is/was void foo(int fp(int){}); intended to be accepted as an
alternate form of that declaration?

look at signature
void foo(int function(int) fp);

it means "function foo which accepts another function which takes 
one int argument and return int value", and it perfectly fine.

but this(void foo(int fp(int){});) is indeed doesn't work with 
DMD, so it may be just outdated stuff from D1, or someone's 
strange idea(may be inspired by something from java?) or anything 
like that.
