Marko A. Rodriguez closed TINKERPOP-1244.
-----------------------------------------
Resolution: Won't Fix
Assignee: Marko A. Rodriguez
This is just pointless additions to the language. Going to close with a "won't
fix." If someone has an argument for doing it, please re-open.
The example I provided in the ticket was:
{code}
g.V().propertyMap().by(properties().count())
{code}
...simply do:
{code}
g.V().map(properties().group().by(key()).by(count()))
{code}
> PropertyMapStep should allow by modulation.

> URL: https://issues.apache.org/jira/browse/TINKERPOP-1244
> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.1.1-incubating
> Reporter: Marko A. Rodriguez
> Assignee: Marko A. Rodriguez
>
> We have {{ProjectStep}} which allows to project traversals off the current
> object. {{PropertyMapStep}} should extend {{ProjectStep}} and then it will
> have {{by()}}-modulation capabilities. Why is this good?
> {code}
> // for each property, how many meta properties does it have?
> g.V().propertyMap().by(properties().count())
> {code}
> A minor thing that gives us a bit more expressivity and allows
> {{ProjectStep}} to take its rightful place as a more fundamental step like
> {{SelectStep}}.
