@asprouse sorry for the delay in getting back to you on this.

Great work and I agree this is something most users would want and expect.

I only have one request, which is to namespace all custom contextual values under lambda. Right now we have lambda_start, lambda_end, etc., but I think it would be cleaner and more intuitive to have them all under lambda unless you have a specific use case in mind for the different event types.

Ultimately I think we will include lambda as a known context in our schema, but this is a good solution for the interim.

@asprouse scratch what I said before. We will be making schema changes related to lambda and then update this code accordingly.

@carkmorwin roger that. Let me know when the when the new version drops.
