Gremlin.Net are proxies to the re

    +most languages do not support lambda introspection and thus, code 
analysis. While Gremlin.Net doesn't support C# lambdas, it
    +is still able to represent lambdas in other languages. When the lambda is 
represented in `Bytecode` its language is encoded
    +such that the remote connection host can infer which translator and 
ultimate execution engine to use.

    Should this be `Lambda.Groovy("{ it.get().value('name').length() }")`, with 
curly brackets?

> 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.
