-------------------------------------------
xiazcy opened a new pull request, #3207:
URL: https://github.com/apache/tinkerpop/pull/3207
As discussed previously (see links in the
[Jira](https://issues.apache.org/jira/browse/TINKERPOP-2234)), this proposal
aims to add a `typeOf` predicate for asserting types in Gremlin.
For maintainability, this also defines a set of core type enum (`GType`) to
be used in Gremlin (which will replace `N` for `asNumber()`), as well as an
overload for String tokens, defined by a global cache for providers to register
their own custom types, and to be recognized by the Grammar.

> Issue Type: Improvement
> Components: process
> Affects Versions: 3.4.2
> Reporter: Stephen Mallette

> Provide for a {{typeOf()}} predicate that allows for testing the type of an
> object which would enable neat things like:
