+# Declarations in stubs
+
+Unlike regular Python modules, stub files often declare module-global variables without initializing
+them. If these symbols are then used in the same stub, applying regular logic would lead to an
+undefined variable access error.
+
+However, from the perspective of the type checker, we should treat something like `symbol: type` the
+same as `symbol: type = ...`. In other words, assume these are bindings too.
+
+```pyi
+from typing import Literal
+
+CONSTANT: Literal[42]
+
+# No error here, even though the variable is not initialized.
+uses_constant: int = CONSTANT
+```
