Yes, I had a feeling compiler should let me have pure ctors..

What about the problem I mentioned at the bottom (if A is a class):

class A {
    float f;
    this (float f) {    // NOT pure
        this.f = f;
    }
    static pure A stworz(float f) {
        return new A(f);
    }
}

This compiles. Should it?
