This code currently compiles:

But this gives an error, as expected:

@bar() void foo(){}

I would expect the first example to give an error too. Is the current
behavior deliberate or is it a DMD bug?
Bug.
Actually the documentation does not treat this at all. However, it is
not the behaviour discussed on the newsgroup.
Note that it introduces a funny little macro system into the language.
Eg. this:
import std.stdio;
int x;
@(write(x++),writeln()) void foo(){}
void main(){
__traits(getAttributes, foo);
__traits(getAttributes, foo)[0];
__traits(getAttributes, foo)[0];
}
Outputs:
0
12
