Interpreters built in Go
For practical start, see this: https://www.youtube.com/watch?v=JiViND-bpmw It explain one particular type of parser type that is quite easy to grasp and fun to write. Also look on some libraries that deliver "expression executors" - these are in fact small interpreted languages and can give you plenty of examples. Classic one (though currently unmaintaines I think) is: https://github.com/PaesslerAG/gval but there are plenty more, just google for them. On my last words, this is very enjoyable part of programming but it requires much learning so be patient and have fun!

My first open-source project looking for feedback
There is a nice lib that let you write much more compact expressions https://github.com/PaesslerAG/gval I'm using this lib for evaluating expressions in a small BPMN engine. At least your solution is missing a context, functions and data to work on. But trying stuff out is propably the best way to learm Go!

CEL on N resources?
There's a simple repl implementation in the cel-go repo that you can use https://github.com/google/cel-go/tree/master/repl/main. But not sure about what you actually want to do though. Has a bit of on XY problem feel to be honest.

Suggestion for a dynamic Struct Validation Rules
https://github.com/google/cel-go Didn't find much support for structs.

Expr - an expression evaluation language for Go
Hello, thanks for sharing - looks awesome. I am currently experimenting with https://github.com/google/cel-go to add some dynamic boolean expressions to my project. Possibly you have heard about Cel and can tell how Expr compares to it?
