An inspection and didactic tools that creates the object from bytes by calling serialize on nested calls to paste0() with detailed comments on what the next line is about.

I thought at 1 point to integrate this as a constructor but it really just makes sense for small objects.

It doesn't need to use the S3 stuff that construct() does, we have one main function, then one function per component, the main function calls the header component helpers first, then we call the appropriate data function, for instance list, and it will recurse by itself. We need to pass an indentation value to the data functions for the recursion to work nicely.
