Hi,
I have just added Closer to MOP support for LispWorks 5.0 to the darcs repository. Before I make this part of the "official" release, I would like to wait a little to see if I get some bug reports. Since I have made the changes directly in the sources of the LispWorks Closer to MOP support, it could be that I have accidentally broken support for older LispWorks version - so feedback in this regard would also be useful.
Cheers, Pascal
