Why addEdge Step does not Natively supports inserting multiple edges for many start and many end vertexes？

[Stark Arya]

Lets see some cases based on ModernGrahp：

1.  2 start& 2 end points。just one edge
 Bad case as I think we need to Reimplementation

2. If we need to add 4 edges，the code seems ugly

Does any one have some ideas。

As i know， neo4j will add 4 edges If we use similar neo4j cypher sql

I think you would prefer the pattern offered by mid-traversal V():

g.V().has('lang', 'java').as('s').

  V().has('lang', 'java').

  addE('link').from('s')

it looks better，but why not try optimize within：
g.addE('work').from(V().has('lang', 'java')).to(V().has('lang', 'java'))

which looks more intuitive

maybe the best answer i can give is that modulators don't work that way. all modulators take only the first item provided in the stream so making addE work differently would create an inconsistency. I also tend to think the explicit nature of the example I provided doesn't really require any improvement in terms of readability or simplicity, so changing addE just adds yet another way to do something that seems to already have a good approach.
