Marko A. Rodriguez updated TINKERPOP3-900:
------------------------------------------
Description:
Right now, this is how you can increment a sack.
{code}
sack{a,b -> a+1}
{code}
OR, lambda free:
{code}
sack(sum).by(constant(1))
{code}
I think we should make a {{by()}}-modulator that is:
{code}
sack(sum).by(1)
{code}
That is:
{code}
by(object) -> by(constant(0)).
{code}
In fact, we have an {{AbstractLambdaTraversal}} called {{ConstantTraversal}}
which will make this even faster (analogous to {{LoopTraversal}} being used
instead of {{until(loops().gt(4))}}.
