Values are the result of evaluating the annotation expressions.
- .. attribute:: FORWARDREF
+ .. attribute:: VALUE_WITH_FAKE_GLOBALS
:value: 2
+ Special value used to signal that an annotate function is being
+ evaluated in a special environment with fake globals. When passed this
+ value, annotate functions should either return the same value as for
+ the :attr:`Format.VALUE` format, or raise :exc:`NotImplementedError`
+ to signal that they do not support execution in this environment.
+ This format is only used internally and should not be passed to
+ the functions in this module.
+
+ .. attribute:: FORWARDREF
+ :value: 3
+
Values are real annotation values (as per :attr:`Format.VALUE` format)
for defined values, and :class:`ForwardRef` proxies for undefined
values. Real objects may contain references to :class:`ForwardRef`
proxy objects.
.. attribute:: STRING
- :value: 3
+ :value: 4
Values are the text string of the annotation as it appears in the
source code, up to modifications including, but not restricted to,
The exact values of these strings may change in future versions of Python.
