That's a good point. Rather, it may even be better to explicitly bind it to T.
This remark made me realize that our Java side writeToString actually
doesn't support *PRINT-CIRCLE* which can be an issue when trying to
debug ABCL before it has loaded the ERROR and PRINT-OBJECT
To make sure it's not forgotten, I've filed a ticket for that.
Thanks for your feedback!
