Collection of practical examples?

[polarathene]

I was hoping for a Learn X in Y minutes overview/breakdown, although with HCL2 that may be overly verbose to cover.

I looked at the top level of the project files and github wiki, there doesn't appear to be any examples beyond the brief snippets in the v1/v2 READMEs and then the granular spec document detailing syntax.

As someone unfamiliar with HCL, but experienced with various other data formats such as JSON/HJSON/TOML/YAML, seeing some more practical examples would be encouraging.

As this repo has a lot of Go code for handling HCL, what is the support for HCL parsing with other languages? (I am not sure how common/discoverable HCL2 support would be outside of Go) Is there a list maintained somewhere? Are there other projects beyond Hashicorp ones using HCL, are any large well known open-source projects?
