Marko A. Rodriguez commented on TINKERPOP3-761:
-----------------------------------------------
I was thinking that we might have a more general pattern we need to realize. We
sort of messed up the mutation steps implementation --- {{addV}}, {{property}},
{{addOutE}}, etc. What did we mess up? --- variables vs. values. I think the
same problem will bite us with these steps if we don't come up with a general
pattern that we should use throughout such steps.
{code}
....as('a')....add('a')
...as('a')..as('b')...add('a','b')
...as('a')....add(2,'a')
....add(2)
...add(...max(), ...sum())
{code}
Variables + values + traversals. What is the general pattern we should use in
Gremlin3 and then propagate that to these math steps as well as to the mutation
steps.

> Issue Type: Improvement

> 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.
