* Trivia and non-trivia tokens are not distinguished on the type level.
* Each token carries its full text.
* The original text can be recovered by concatenating the texts of all tokens in order.
* Accessing a child of particular type (for example, parameter list of a function) generally involves linerary traversing the children, looking for a specific `kind`.
* Accessing a child of particular type (for example, parameter list of a function) generally involves linear traversing the children, looking for a specific `kind`.
* Modifying the tree is roughly `O(depth)`.
We don't make special efforts to guarantee that the depth is not linear, but, in practice, syntax trees are branchy and shallow.
* If mandatory (grammar wise) node is missing from the input, it's just missing from the tree.
