:pep:`572`: As described in the PEP, assignment expressions now raise

:exc:`SyntaxError` when their interaction with comprehension scoping results

:exc:`ImportError` with a message explaining that the module isn't supported
|
|
on Windows. On other platforms, if the underlying ``_crypt`` module is not
|
|
available, the ImportError will include a message explaining the problem.
