[Python-Dev] test_string, test_unicode fail

[Guido van Rossum]

Today, test_string and test_unicode have started to fail.  I'm
suspicious that this is the result of changes Marc-Andre checked in to
make unicode() behave more like str().

A little investigation (not that the string test suite makes this easy
:-( ) shows that line 133 of string_tests.py checks to make sure that

    '.'.join('a', u'b', 3)

raise an exception.  But it now silently casts the 3 to u'3', so the
result is u'a.b.3'.

Is this really an good idea?  Was it an intended side effect?

Also, Marc-Andre, please run the full test suite and check its results
before checking in changes like this.
