---------------------------------------------

Might be more palatable to do if TINKERPOP-1417 was in place.

> 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}
