This is accepts-valid behavior.

function(parameters) => expr

means the combination of:

1. specifying "context pointer is not necessary"

2. lambda syntax "(parameters) => expr"

I think website documentation has a bug.

While finishing up work on my parser and grammar specification I found this in container.d:

return equal!(function(Elem a, Elem b) => !_less(a,b) && !_less(b,a))
                     (thisRange, thatRange);

It seems to be some strange hybrid of the function literal syntax and the lambda syntax. It's not documented anywhere (surprise!) and I'm not sure if I should support it or file an accepts-invalid bug against DMD.
