If one were to create their own language and documentation for the language, could they ask for a review on code they have written in their language as long as they provided a link or inline documentation?
The asker would have do more than provide a link to documentation or inline documentation.
There needs to be an existing compiler or interpreter for the language. There needs to be a way for potential reviewers to actually run the code.
If the code cannot be compiled/interpreted and ran, then the code is nothing but a special syntax of pseudo-code.
