"""Run Python's standard test suite using importlib.__import__.

Tests known to fail because of assumptions that importlib (properly)
invalidates are automatically skipped if the entire test suite is run.
Otherwise all command-line options valid for test.regrtest are also valid for
this script.

XXX FAILING
    test_builtin  # Wanting a TypeError for an integer name
    test_import  # execution bit, exception name differing, file name differing
                    between code and module (?)
    test_importhooks  # package not set in _gcd_import() but level > 0
    test_pep3120  # Difference in exception
    test_runpy  # Importing sys.imp.eric raises AttributeError instead of
                    ImportError (as does any attempt to import a sub-module
                    from a non-package, e.g. tokenize.menotreal)
