["Marko A. Rodriguez (JIRA)" <ji...@apache.org>]

Marko A. Rodriguez commented on TINKERPOP-1409:
-----------------------------------------------

I was thinking about it last  night and thought that if the result is "null" we simply don't print anything.

{code}
gremlin> aVoidFunction()
gremlin> 1+2
==>3
gremlin> null
gremlin> [null, null]
==>null
==>null
gremlin>
{code}

> A common question among new users is what is with the "null" return String in the console when there is a successful execution.  An explanation is in the docs now (see note at bottom of http://tinkerpop.apache.org/docs/current/reference/#_mutating_the_graph section) but it would be nice to avoid it or make it more immediately understandable for new users.
> It's not a huge deal, but often comes up as a question from new users.
