# Purity
Because a lambda needs to access the frame, any function using 
the lambda trick can't be made pure:
void foo(T)(T a) @safe
{
    (){
        ++a;
    }();
}
Error: pure function 'main.foo' cannot call impure function 
literal '__lambda1'


In case of lambda, purity does the wrong thing. The behavior is 
bogous.
