// This file describes the AST classes.
// It tries to stay as close as possible to the AST defined by CPython at
// https://docs.python.org/3/library/ast.html.
// The base type from which all AST classes derive is iast.
// For every left hand side entity in the CPython AST definition there is
// a corresponding lower case trait with an "i" prefixed, if there is
// more than one right hand side entity. Otherwise the left hand side
// entity becomes a class with a capitalized start character.
// E.g. stmt => istmt
// arguments => Arguments
//
// There are some deviations from the CPython AST.
// 1. expr_context is omitted since deriving whether e.g. an attribute is
// a "load", "store" or "del" is context sensitive and we do not want
// to keep that context during parsing.
// 2. type_ignore and type_comment are currently not populated as comments
// are currently not put in the normal token stream. This could become
// a TODO if we need it at some point.
// 3. We added an ErrorStatement in order to reflect parse errors inline
// with the code we parsed successfully.
// 4. We added a StringExprList since we do not want to combine string
// constants during parsing. This allows us to be more fine grained
// in terms of string prefixes like r"someString" or b"someBytes".
// 5. Constants are not evaluated during parsing. E.g. CPython generates
// an integer constant reflecting the integer value for "0x11" whereas
// we just keep the string representation.
// In general expect the constant representation to be different from
// CPythons.
