**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** In non-rust bindings where Rust Enum inspection is not present it is difficult to understand which `Expr` variant you are interacting with. It would be much easier in bindings written in languages like Python for example, to have the ability to invoke a function on an `Expr` variant instance and be return a String representation of that variant. Something named obviously like `variant_name()` **Describe the solution you'd like** Function added to `Expr` that returns a `String` representation of the current variant represented by the `Expr` instance the function is called on. **Describe alternatives you've considered** Thought about using Macros and adding similar blanket coverage for all instance types but that seems to heavy and I personally often find heavy macro use in the code base unclear. **Additional context** PyO3 is a popular binding library for Python and Rust. There is currently no support for directly introspecting Rust Enums and hence why this change would be nice to have. -- This is an automated message from the Apache Git Service.
