>             Project: TinkerPop 3
>          Issue Type: Improvement
>          Components: process
>    Affects Versions: 3.0.2-incubating
>            Reporter: Matt Frantz
>            Assignee: Marko A. Rodriguez
>            Priority: Minor

>             Fix For: 3.1.0-incubating

> To improve type safety in the {{property}} step, we should change the interface from ...
> {noformat}
> property(VertexProperty.Cardinality cardinality, Object key, Object value, Object...keyValues)
> property(Object key, Object value, Object...keyValues)
> {noformat}
> ... to ...
> {noformat}
> property(VertexProperty.Cardinality cardinality, String key, Object value, Object...keyValues)
> property(String key, Object value, Object...keyValues)
> property(VertexProperty.Cardinality cardinality, T key, Object value, Object...keyValues)
> property(String key, T value, Object...keyValues)
> {noformat}
> Specifically, this makes it explicit that keys may only be {{T}} or {{String}} type. 
> This would  NOT address the lack of type safety in the variadic {{keyValues}} list.
> This is a breaking change for application developers, since it makes the key type more specific.  However, it does not restrict the actual values supported, as key values that were not {{T}} or {{String}} would have been rejected at runtime previously.
