Is there an interface for getting schema information directly? #497

When you are doing codegen for a language binding, you need to get the schema information of a Pkl schema. I know in pkl-swift it basically just concatenates the schema and the Pkl codegen source code written in Pkl in a Pkl file and let's the evaluator do the codegen, but I don't wanna write codegen code in Pkl. As awesome as Pkl is, this is too much pickling for me. |

You can get this information from the reflect API, which you can then render into JSON/YAML/whatever else. Alternatively, if you are in Java, you can use BTW: What are you looking to do codegen for? NOTE: there is a bug that prevents you from rendering reflect values in 0.25 that is now fixed in 0.26.0-dev (docs for downloading dev executables here: https://pkl-lang.org/main/latest/pkl-cli/index.html#download) |

An interface like that would be useful for generating structs/classes for easy serialisation and deserialisation using a Pkl schema. |
