Some lambdas are very simple data transformations.
Now you can do them in dhall!
Add your main logic in /src/function.dhall, run make zip and deploy :)
For a local test, you can run it with sam-cli
For example the example function can be run with:
sam local invoke -e events/john.dhall
or
sam local invoke -e events/jane.dhall
Status: not production ready! It's probably possible to inject malicious code in the input right now, so use just for fun and don't give the lambda any permissions.
