Nevin,
Thank you for pointing this out.
The change in question was made in service of tracking down residual users of a deprecated protocol during debugging, and was (obviously) not made with reference to any non-Squeak usage.
A reasonable fix is indeed simply to revert the method, as suggested; this remedy will will appear in a forthcoming update soon unless objections are heard.
Sorry for the hassle, and cheers,
-- Scott

In change set 5051u62, the implementation of ClassDescription>>classComment: was changed from:

This change effectively breaks Squeak from being able to file in VisualWorks 3.0 chunk format fileins. I have found the interoperability for fileins between VW and Squeak to be very useful. In fact, my Squeak GLORP port just uses the VW GLORP filein directly. But, this change broke that ability.
So, what was the rationale for making that change in Squeak? Is there any chance we can get it set back to what it was?
