>                 URL: https://issues.apache.org/jira/browse/TINKERPOP-1882
>             Project: TinkerPop
>          Issue Type: Improvement
>          Components: process
>    Affects Versions: 3.2.7, 3.3.1
>            Reporter: Florian Hockmann
>            Assignee: Daniel Kuppitz
>            Priority: Minor
>
> For a traversal like
> {{g.V(a).out().valueMap().limit(123)}}
> we can simply move the {{limit()}} to the left so we get:
> {{g.V(a).out().limit(123).valueMap()}}
> This avoids unnecessary database lookups.
> We should create a strategy that moves the {{limit}} and the {{range}} step like this to _the left_  for all {{map}} steps.
