I think, it would be beter to do:
(a) return isInShadowTree() or,
(b) remove this method and replace other code (using isScope()) with
isInShadowTree().

I'll take the (b) approach.
Less "scope" terminology usage will make the code more readable.

We still need m_scoped? I think, we could replace this with isInShadowTree().

[kochi, 2014/06/03 07:47:05]

Removed.
