Marko A. Rodriguez commented on TINKERPOP3-669:
-----------------------------------------------
We could create a Step interface called {{RequiresStrategy}}. Its a special
interface that when the traversal is submitted, the steps are scanned for
required strategies and then they are added. The problem, a resort of the
strategies on each traversal creation off of traversal source.

> As we now execute the Gremln process suite with and without strategies
> applied, it became apparent that some strategies are simply "required". See:

> Not sure what this means in the grand scheme of things. A few things that
> feel weird or require more thought:
> 1. Kinda weird that a {{Traversal}} requires any strategies at all to execute.
> 2. Kinda weird that a {{Step}} should know anything about strategies as is
> the case with {{ConjunctionStrategy}} for example.
> 3. If required strategies are expected then should those required strategies
> be somewhere more prominently maintained/documented/etc than just being
> relegated to the test suite
> Not sure anything really needs to change here, just wanted to create an issue
> for future thought.
