I asked John Williams, the main Lisp implementor in the Poplog
development team (at ISL and Sussex University) and he said:
"Poplog 15 Common Lisp is a near-complete implementation of
CLtL2, the only omissions being user-defined method combination,
the new pretty printer, and `compile-file'".

The online Poplog Lisp News file states:
1994 Apr 28 (John Williams)
o Poplog Common Lisp now includes an almost complete implementation
of CLOS (the Common Lisp Object System) as discussed in Steele 1990,
Chapter 28. The main omission is that currently only standard method
combination is supported.
But I can't comment on how well it is implemented. If you fetch the
free Linux Poplog from
ftp://ftp.cogs.susx.ac.uk/pub/poplog/poplog15.0
you'll be able to check for yourself, and perhaps post a summary.
