Gremlin bindings methods support

In gremlin docs they describe the use of bindings to reduce the overhead of compilation.

g.V(('id',1)).out('created').name.toList()

I tried to do the same on has method, but it didn't work

g.V().has('some_attribute', 'x', 'some_value')

Which methods can be improved using bindings? Can bindings be used on other methods as well besides V()?

Bindings will work on any script you pass to Gremlin Server. In your examples though I don't see where those scripts would make use of bindings at all. Your first example doesn't appear to look valid. It should be something like:

g.V(x).out('created').values('name')

where "x" is a binding passed on the request with a value of "1".

Your second example should be something like:

g.V().has('name', x)

where "x" is a binding passed on the request with the value to match for the 'name' property. I'm just making that last one up as I didn't understand the original traversal too well and what you wanted parameterized.
