+"""Test for mypy extension package import crash regression.

+This reproduces the crash described in issue #10223 where importing
+mypy modules with --extension-pkg-allow-list=mypy caused an AttributeError
+crash due to mypyc-compiled objects not having __dict__ attributes.
+
+The fix ensures this generates an import-error message instead of crashing.
