You're right, we should solve this problem, but I think that the changes
for that are big enough to validate its own issue and it's also somewhat
unrelated to this PR. So I created a new issue for that:
[TINKERPOP-1901](https://issues.apache.org/jira/browse/TINKERPOP-1901). I
suggest that we resolve that one first and then I simply rebase this PR
afterwards and let the `Lambda` class implement whichever interface we
introduce there for those cases.
> Support lambdas in Gremlin.Net
> ------------------------------
>
> Key: TINKERPOP-1854
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1854
> Project: TinkerPop
> Issue Type: Improvement
> Components: dotnet
> Affects Versions: 3.3.0, 3.2.6
> Reporter: Florian Hockmann
> Assignee: Florian Hockmann
> Priority: Major
>
> Gremlin.Net should support lambdas. We already discussed this in [the pull
> request for TINKERPOP-1752|https://github.com/apache/tinkerpop/pull/712].
> Here is what [~spmallette] said over there:
> {quote}
> Any reason we don't support lambdas? Even if .NET can't support them natively
> for some reason wouldn't we minimally support the ability to pass a
> python/groovy/etc lambda? it's kinda weird that way, but i think back to the
> point that kuppitz made on the dev list the other day where he stated that he
> doesn't always find a way out of using lambdas in production systems he works
> on - so ultimately users will need that kind of capability i think.
> {quote}
> C# lambdas would require some kind of C# parser on the server side, so at
> least in the beginning a way to send lambdas from already supported languages
> in Gremlin.Net should be enough.
