EMPTY_FILE, // A script file is empty.
DEPRECATED_KEYWORD, // The keyword is deprecated and should be replaced.
RENAMED_IN_GODOT_4_HINT, // A variable or function that could not be found has been renamed in Godot 4.
CONFUSABLE_IDENTIFIER, // The identifier contains misleading characters that can be confused. E.g. "usеr" (has Cyrillic "е" instead of Latin "e").
CONFUSABLE_LOCAL_DECLARATION, // The parent block declares an identifier with the same name below.
CONFUSABLE_LOCAL_USAGE, // The identifier will be shadowed below in the block.
INFERENCE_ON_VARIANT, // The declaration uses type inference but the value is typed as Variant.
NATIVE_METHOD_OVERRIDE, // The script method overrides a native one, this may not work as intended.
GET_NODE_DEFAULT_WITHOUT_ONREADY, // A class variable uses `get_node()` (or the `$` notation) as its default value, but does not use the @onready annotation.
ONREADY_WITH_EXPORT, // The `@onready` annotation will set the value after `@export` which is likely not intended.
