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.
