stephen mallette commented on TINKERPOP-1866:
---------------------------------------------
I don't know if it provides much value in 2.0....not sure of any other
circumstance where it would be returned as part of a traversal. afaik,
{{valueMap(true)} is the only use case. not sure if anyone else can think of a
reason to have it supported for GraphSON 2.0. Note that "support" in this case
does mean "when {{T}} is returned from the server, not when sent to the
server". We already support {{T}} being serialized generally as an enum to the
server in GraphSON 2.0.

> Key: TINKERPOP-1866
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1866
> Project: TinkerPop
> Issue Type: Improvement
> Components: dotnet
> Affects Versions: 3.3.1
> Reporter: stephen mallette
> Assignee: Jorge Bay
> Priority: Critical
>
> We didn't have tests for return of {{T}} which can occur with
> {{valueMap(true)}} - adding them on TINKERPOP-1860 exposed the failure in
> .NET. This may or may not be an issue for GraphSON 3.0 only. In GraphSON 2.0,
> {{g:T}} is a defined type, but it is typically not returned from the server
> outside of {{valueMap(true)}}. When that did happen in GraphSON 2.0, {{T}}
> values were simply converted to string.
