The Rust re-write is being worked on in a separate repo: https://github.com/pydantic/pydantic-core

Another tool in this space is Dasel[1], which can handle querying/modifying JSON, YAML, TOML, XML and CSV files.

I do prefer that to jq syntax, as well as alternatives jello and yamlpath.

Since Wing compiles to Terraform, you should be able to manually run Infracost (https://www.infracost.io) to get an idea of costs.

Having that capability baked into the language/compiler would be a great addition.

Infracost is OK. It's not great, it's OK. To not be meaningless, it's not always accurate, still has some bugs, doesn't cover everything. But it's still the best tool in its class and I use it.

If the value proposition of a cloud language included "infracost but better", I might be more inclined to listen.

I'm co-founder of Infracost, happy to chat more about how we can make it great :) feel free to join the community chat if you want to DM me: https://www.infracost.io/community-chat

[Wing team member here] We are looking into adding cost gauging and cost cutting abilities in Wing in the future. Right now we are focusing on the basics of the language. You are welcome to join our GitHub repo and vote on the features that are important for you.
