+# `global` references
+
+## Implicit global in function
+
+A name reference to a never-defined symbol in a function is implicitly a global lookup.
+
+```py
+x = 1
+
+def f():
+    reveal_type(x)  # revealed: Unknown | Literal[1]
+```
+
+## Explicit global in function
+
+```py
+x = 1
+
+def f():
+    global x
+    reveal_type(x)  # revealed: Unknown | Literal[1]
+```
+
+## Unassignable type in function
+
+```py
+x: int = 1
+
+def f():
+    y: int = 1
+    # error: [invalid-assignment] "Object of type `Literal[""]` is not assignable to `int`"
+    y = ""
+
+    global x
+    # TODO: error: [invalid-assignment] "Object of type `Literal[""]` is not assignable to `int`"
+    x = ""
+```
+
+## Nested intervening scope
+
+A `global` statement causes lookup to skip any bindings in intervening scopes:
+
+```py
+x: int = 1
+
+def outer():
+    x: str = ""
+
+    def inner():
+        global x
+        # TODO: revealed: int
+        reveal_type(x)  # revealed: str
+```
+
+## Narrowing
+
+An assignment following a `global` statement should narrow the type in the local scope after the
+assignment.
+
+```py
+x: int | None
+
+def f():
+    global x
+    x = 1
+    reveal_type(x)  # revealed: Literal[1]
+```
+
+## `nonlocal` and `global`
+
+A binding cannot be both `nonlocal` and `global`. This should emit a semantic syntax error. CPython
+marks the `nonlocal` line, while `mypy`, `pyright`, and `ruff` (`PLE0115`) mark the `global` line.
+
+```py
+x = 1
+
+def f():
+    x = 1
+    def g() -> None:
+        nonlocal x
+        global x  # TODO: error: [invalid-syntax] "name 'x' is nonlocal and global"
+        x = None
+```
+
+## Global declaration after `global` statement
+
+```py
+def f():
+    global x
+    # TODO this should also not be an error
+    y = x  # error: [unresolved-reference] "Name `x` used when not defined"
+    x = 1  # No error.
+
+x = 2
+```
+
+## Semantic syntax errors
+
+Using a name prior to its `global` declaration in the same scope is a syntax error.
+
+```py
+x = 1
+
+def f():
+    print(x)  # TODO: error: [invalid-syntax] name `x` is used prior to global declaration
+    global x
+    print(x)
+
+def f():
+    global x
+    print(x)  # TODO: error: [invalid-syntax] name `x` is used prior to global declaration
+    global x
+    print(x)
+
+def f():
+    print(x)  # TODO: error: [invalid-syntax] name `x` is used prior to global declaration
+    global x, y
+    print(x)
+
+def f():
+    global x, y
+    print(x)  # TODO: error: [invalid-syntax] name `x` is used prior to global declaration
+    global x, y
+    print(x)
+
+def f():
+    x = 1  # TODO: error: [invalid-syntax] name `x` is used prior to global declaration
+    global x
+    x = 1
+
+def f():

+    x = 1  # TODO: error: [invalid-syntax] name `x` is used prior to global declaration

+    global x, y

+

+    del x  # TODO: error: [invalid-syntax] name `x` is used prior to global declaration
+    global x
+    del x
+
+def f():
+    del x  # TODO: error: [invalid-syntax] name `x` is used prior to global declaration

+    global x
+
+# still an error in module scope
+x = None  # TODO: error: [invalid-syntax] name `x` is used prior to global declaration
+global x
