 [`typing.Final`] is a type qualifier that is used to indicate that a symbol may not be reassigned in
 any scope. Final names declared in class scopes cannot be overridden in subclasses.
 
-## Basic
+## Basic type inference
+
+### `Final` with type
+
+Declared symbols that are additionally qualified with `Final` use the declared type when accessed
+from another scope. Local uses of the symbol will use the inferred type, which may be more specific:
 
 `mod.py`:
 
 ```py
 from typing import Final, Annotated
 
-FINAL_A: int = 1
+FINAL_A: Final[int] = 1
 FINAL_B: Annotated[Final[int], "the annotation for FINAL_B"] = 1
 FINAL_C: Final[Annotated[int, "the annotation for FINAL_C"]] = 1
-FINAL_D: Final = 1
-FINAL_E: "Final[int]" = 1
+FINAL_D: "Final[int]" = 1
+FINAL_F: Final[int]
+FINAL_F = 1
 
 reveal_type(FINAL_A)  # revealed: Literal[1]
 reveal_type(FINAL_B)  # revealed: Literal[1]
 reveal_type(FINAL_C)  # revealed: Literal[1]
 reveal_type(FINAL_D)  # revealed: Literal[1]
-reveal_type(FINAL_E)  # revealed: Literal[1]
+reveal_type(FINAL_D)  # revealed: Literal[1]
 
-# TODO: All of these should be errors:
-FINAL_A = 2
-FINAL_B = 2
-FINAL_C = 2
-FINAL_D = 2
-FINAL_E = 2

+    reveal_type(FINAL_C)  # revealed: int
+    reveal_type(FINAL_D)  # revealed: int
+    reveal_type(FINAL_F)  # revealed: int
 ```

+Imported types:
 
 ```py
-from mod import FINAL_A, FINAL_B, FINAL_C, FINAL_D, FINAL_E
+from mod import FINAL_A, FINAL_B, FINAL_C, FINAL_D, FINAL_F
 
-# TODO: All of these should be Literal[1]

-reveal_type(FINAL_E)  # revealed: int
+reveal_type(FINAL_D)  # revealed: int
+reveal_type(FINAL_F)  # revealed: int
+```
+
+### `Final` without a type
+
+When a symbol is qualified with `Final` but no type is specified, the type is inferred from the
+right-hand side of the assignment. We do not union the inferred type with `Unknown`, because the
+symbol cannot be modified:
+
+`mod.py`:
+
+```py
+from typing import Final
+
+FINAL_A: Final = 1
+
+reveal_type(FINAL_A)  # revealed: Literal[1]
+
+def nonlocal_uses():
+    reveal_type(FINAL_A)  # revealed: Literal[1]
+```
+
+`main.py`:
+
+```py
+from mod import FINAL_A
+
+reveal_type(FINAL_A)  # revealed: Literal[1]
+```
+
+### In class definitions
+
+```py
+from typing import Final
+
+class C:
+    FINAL_A: Final[int] = 1
+    FINAL_B: Final = 1
+
+    def __init__(self):
+        self.FINAL_C: Final[int] = 1
+        self.FINAL_D: Final = 1
+
+reveal_type(C.FINAL_A)  # revealed: int
+reveal_type(C.FINAL_B)  # revealed: Literal[1]
+
+reveal_type(C().FINAL_A)  # revealed: int
+reveal_type(C().FINAL_B)  # revealed: Literal[1]
+reveal_type(C().FINAL_C)  # revealed: int
+# TODO: this should be `Literal[1]`
+reveal_type(C().FINAL_D)  # revealed: Unknown
+```
+
+## Not modifiable
+
+Symbols qualified with `Final` cannot be reassigned, and attempting to do so will result in an
+error:
+
+```py
+from typing import Final, Annotated
+
+FINAL_A: Final[int] = 1
+FINAL_B: Annotated[Final[int], "the annotation for FINAL_B"] = 1
+FINAL_C: Final[Annotated[int, "the annotation for FINAL_C"]] = 1
+FINAL_D: "Final[int]" = 1
+FINAL_E: Final[int]
+FINAL_E = 1
+FINAL_F: Final = 1
+
+# TODO: all of these should be errors
+FINAL_A = 2
+FINAL_B = 2
+FINAL_C = 2
+FINAL_D = 2
+FINAL_E = 2
+FINAL_F = 2
