The .net build is failing:

> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.3.0
> Reporter: Daniel Kuppitz
>
> We already have a a set of default BiFunctions / operators, that are not
> treated as lambdas. We should also have a bunch of simple functions, that can
> then be used in {{map()}} or {{sack()}} and that can be serialized as
> bytecode. For example:
> {noformat}
> ...map(sqrt)
> ...map(log)
> ...sack(sigmoid) // compute sigmoid of the current sack and update the
> sack
> ...sack(cos).by("x") // compute the cosine of the current element's "x" and
> assign / overwrite the current sack value
> {noformat}
