BTW, why doesn't this example work with lambdas (a => a != 2)
instead of a string mixin ("a != 2")?

I think lambda instantiations defines a different type. So it's
incompatible.

Incompatible with what? I meant changing it in both the declaration
and the initialization.

Lambdas are not "cached", so each lambda is unique even if it's code is
the same:

     void main(){
         pragma(msg,(int a)=>a); //prints __lambda1
         pragma(msg,(int a)=>a); //prints __lambda2
     }


At any rate, you can't use lambdas(neither `delegate` nor `function`)
when declaring a member of class or struct, since D will treat it as a
method(rather than a static function) and complain about the `this`
reference.

I think there was either or both a discussion and a bug report on this, but can't find either. Basically we need to clarify what it means to compare two function literals for equality. -- Andrei
