CLI, Help match open/close characters

In a context where we have a nesting of complex objects as operation parameters, it is difficult to match the '{' and '[' with their closing counterparts.

We could imagine something similar to IDE editor where such characters are automatically matched and colorised.

When moving the cursor onto a closing character, the opening character should be highlighted. If no match is found, then the current closing character should be also highlighted (e.g.: in red to make it clear that it is an error).
