DSpec / Templates + Delegates

[Masahiro Nakagawa]

Hi,

I read sources. I have something on my chest.

- ruun package
Umm...need?

- import ruun.dspec.Spec; import ruun.dspec.Should;
I think ruun.dspec.Spec should uses "public import" for Should module.
Is there a case that spec empties in it! ?

- Spec methods
Why final? How can I create custom Spec?

I expect the maturation of this project in a good direction.
