Regarding the `match()` translation, it's indeed very easy:
```
gremlin> g.V().as("a").outE("created").as("b").
......1> inV().as("c").in("created").as("d").
......2> match(
......3> __.as("a").values("age").as("a_by"),
......4> __.as("b").values("weight").as("b_by"),
......5> __.as("c").in("created").values("age").min().as("c_by"),
......6> __.as("d").values("age").as("d_by"),
......7> ).
......8> where("a_by", lt("b_by").or(gt("c_by")).and(neq("d_by"))).
......9> select("a", "c", "d").by("name")
==>[a:josh,c:lop,d:marko]
==>[a:josh,c:lop,d:peter]
==>[a:peter,c:lop,d:marko]
==>[a:peter,c:lop,d:josh]
```
I will make a code review and vote tomorrow.
> by()-modulation for where()

> Key: TINKERPOP-1330
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1330
> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.2.1
> Reporter: Daniel Kuppitz
> Assignee: Marko A. Rodriguez
>
> As discussed in https://issues.apache.org/jira/browse/TINKERPOP-1329, it
> would be nice to have {{by()}}-modulators for {{where()}}. For example:
> {code}
> g.V().as("a").out().where(gt("a")).by("age") // both a and current ages are
> selected
> g.V().as("a").out().as("b").where("b",gt("a")).by("age") // both a and b ages
> are selected
> g.V().as("a").out().as("b").where("b",gt("a")).by("age").by("weight") //
> where b.age > a.weight
> {code}
