class SymbolTableNode:
    """Description of a name binding in a symbol table.

    These are only used as values in module (global), function (local)
    and class symbol tables (see SymbolTable). The name that is bound is
    the key in SymbolTable.

    Symbol tables don't contain direct references to AST nodes primarily
    because there can be multiple symbol table references to a single
    AST node (due to imports and aliases), and different references can
    behave differently. This class describes the unique properties of
    each reference.

    The most fundamental attribute is 'node', which is the AST node that
    the name refers to.

    The kind is usually one of LDEF, GDEF or MDEF, depending on the scope
    of the definition. These three kinds can usually be used
    interchangeably and the difference between local, global and class
    scopes is mostly descriptive, with no semantic significance.
    However, some tools that consume mypy ASTs may care about these so
    they should be correct.

    Attributes:
        _node: AST node of definition. Among others, this can be one of
            FuncDef, Var, TypeInfo, TypeVarExpr or MypyFile -- or None
            for cross_ref that hasn't been fixed up yet. Should not be accessed
            directly, only via the `node` property.
        kind: Kind of node. Possible values:
               - LDEF: local definition
               - GDEF: global (module-level) definition
               - MDEF: class member definition
               - UNBOUND_IMPORTED: temporary kind for imported names (we
                 don't know the final kind yet)
        module_public: If False, this name won't be imported via
            'from <module> import *'. This has no effect on names within
            classes.
        module_hidden: If True, the name will never be exported (needed for
            stub files)
        cross_ref: For deserialized MypyFile nodes, the referenced module
            name; for other nodes, optionally the name of the referenced object.
        implicit: Was this defined by assignment to self attribute?
        plugin_generated: Was this symbol generated by a plugin?
            (And therefore needs to be removed in aststrip.)
        no_serialize: Do not serialize this node if True. This is used for internal
            and/or temporary symbols such as function redefinitions.
        unfixed: Indicates that this symbol is fresh after deserialization and
            needs fixup, such as resolving cross-references etc.
        stored_info: TypeInfo containing this symbol. Normally code accesses this
            on the `node` attribute, but it may be not ready during deserialization,
            so we temporarily store info on the symbol itself.

    NOTE: No other attributes should be added to this class unless they
    are shared by all node kinds.
