 The reason behind the first limitation is that `Table` does not store its header, 
 allowing us to safely swap two tables (we store a mapping in each table: child key -> child table).
 
 This last two limitations allow us to represent a toml document as a tree-like data structure, 
 which enables easier implementation of editing operations
