Major Description
There is a bunch of hackery to generate:
g.withSack((java.util.function.Supplier) {1.0d}, (java.util.function.UnaryOperator) {it + 1}).
V().sack()
It would be nice if that was just:
g.withSack({1.0d}, {it + 1}).V().sack()
in earlier version we get this:
gremlin> g.withSack(1.0d, {it + 1}).V().sack()
Ambiguous method overloading for method org.apache.tinkerpop.gremlin.process.traversal.dsl.graph.GraphTraversalSource#withSack.
Cannot resolve which method to invoke for [class java.lang.Double, class groovysh_evaluate$_run_closure1] due to overlapping prototypes between:
[class java.lang.Object, interface java.util.function.BinaryOperator]
[class java.lang.Object, interface java.util.function.UnaryOperator]
Type ':help' or ':h' for help.
