Stephen Mallette updated TINKERPOP-3129:
----------------------------------------
Description:
Gremlin has several pattern for getting all elements in the stream except for
the last one. Here's one way to do it:
{code}
fold().sideEffect(tail(local).store('t')).
unfold().where(neq('t')).by().by(unfold())
{code}
The set of collection manipulation steps would benefit from an easier way to do
this.
