             Summary: Avoid exceptions on local scope based steps where possible
                 Key: TINKERPOP-2890
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-2890
             Project: TinkerPop
          Issue Type: Improvement
          Components: process
    Affects Versions: 3.5.5
            Reporter: Stephen Mallette


If you {{g.inject([1,2], 1])dedup(local)}} you get an casting error because "1" 
is not an {{Iterable}} and {{local}} only works with that type. Would be better 
if a {{dedup()}} of a non-iterable just returned the object itself. Consider 
other steps that use {{local}} and make similar improvements there for 
consistency.
