Marko A. Rodriguez commented on TINKERPOP3-761:
-----------------------------------------------
I created TINKERPOP3-799. Few things to your comment.
1. You can't extend String. If you want the String value, just don't {{with()}}
it. {{...addV('name','x').with('x',select('a').values('name'))}}
2. I don't see this as the same thing as TINKERPOP3-655 as
{{with()}}-modulation would only be applied to steps that can reasonably
leverage it -- i.e. not every step.
3. {{select().with('a',...)}} is a nice idea. However, I would say we make it
{{select().by('a',...)}} if people want to be explicit. We can't mix the
meaning of {{with()}} and {{by()}}. One if for changing the arguments of a step
on a per object basis ({{with()}}). The other is for modulating the incoming
values of a step ({{by()}}).

> Key: TINKERPOP3-761
> URL: https://issues.apache.org/jira/browse/TINKERPOP3-761
> Project: TinkerPop 3
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.0.0-incubating
> Reporter: Daniel Kuppitz
> Assignee: Marko A. Rodriguez
>
> Every once in a while I wish to have steps for some basic mathematical
> operations ({{add()}}, {{sub()}}, {{mul()}}, {{div()}}). Since {{sub(num)}}
> is the same as {{add(-num)}} and {{div(num)}} is the same as {{mul(1/num)}},
> we would only need two new step implementations.
> Oh, and then there's also {{mod()}}, thus 3 new step implementations.
