Daniel Kuppitz commented on TINKERPOP-1387:
-------------------------------------------
Hmm, {{select("a")}} selects all a's. Hence {{path().from("a")}} should also
use all a's. Let me use an easier example:
{code}
gremlin> g.V().as('a').out().as('a').out().as('b').path().from('a').to('b')
==> [[v[1],v[4],v[5]],[v[4],v[5]]]
==> [[v[1],v[4],v[3]],[v[4],v[3]]]
{code}
{{.from("a").to("a")}} is crazy though.
> from and to modulators for path steps

> Just had this crazy idea of {{from}} and {{to}} modulators for path steps.
> {code}
> g.V(1).as("a").
>
> repeat(both("knows").simplePath().from("a")).emit().out("created").as("p").in("created").
>
> repeat(both("knows").simplePath().from("p")).emit(hasId(6)).out("created").as("b").
> path().from("a").to("p").as("pathFromMarkoToProject").
> path().from("p").to("b").as("pathFromProjectToPeter").
> match(
> __.as("pathFromMarkoToProject").count(local).is(lte(3)),
> __.as("pathFromProjectToPeter").count(local).is(lte(3))
> ).select("p", "pathFromMarkoToProject", "pathFromProjectToPeter")
> {code}
