             Summary: Should a head-as("x") always be a select("x")?
                 Key: TINKERPOP-1496
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-1496
             Project: TinkerPop
          Issue Type: Improvement
          Components: process
    Affects Versions: 3.2.2
            Reporter: Marko A. Rodriguez


There are two steps that treat a head of {{as("x")}} as {{select("x")}}. 

{code}
match(as("x").out().as("y"), ...) => match(select("x").out().as("y"), ...)
where(as("x").has("name")) => where(select("x").has("name"))
{code}

I don't like how these steps are "special" in this respect and I think that it would be elegant if a head-{{as()}} has a consistent meaning for all inner traversals.

Thus, I'm wondering if we should make it such that EVERY head {{as("x")}} gets translated to {{select("x")}}.

{code}
addE("knows").to(as("x").out("mother"))
property("name", as("x").out("mother").values("name"))
{code}

I believe this would be backwards compatible in the sense that there really isn't a reason why an inner traversal head-{{as()}} would be used to label. Dunno -- definitely need [~dkuppitz]/etc. feedback.
