MySQL is not supported under Python 3 for SQLAlchemy

[kceiw]

As far as I know and in my project, SQLAlchemy supports Python 3 even though MySQL is used. I'm considering to use bottle-cork in my project. But when I read the source file (sqlalchemy_backend.py) and found warning that SQLAlchemy doesn't support Python3 when MySQL is used. I wonder what's blocking SQLAlchemy backend to use MySQL in Python 3. If it's not the case, can we remove that warning?
