Hi,

In the grammar for Declarations, 
  http://www.digitalmars.com/d/declaration.html
there is:

Declarator:
 BasicType2 Declarator
 Identifier
 () Declarator 
 Identifier DeclaratorSuffixes
 () Declarator  DeclaratorSuffixes

the "() Declarator" parts, are they Ok ?

Should that be written "( Declarator )" instead ?

Yep. There have been a few of these misplaced parens since the spec was moved over to DDoc. Although, what is this syntax for? int (x) = 5; writefln(x); This works. Why would you want to put parens there?

The only thing I can think of is support for C-style function pointer declerations, but I thought we wanted to move away from those... The compiler still accepts and comprehends them, though. -- Chris Nicholson-Sauls
