It was not rejected; the CLOS designers decided that they could not produce a completely satisfactory spec in time for the X3J13 draft and withdrew their intention to standardise that part of CLOS at this time. This was formally announced at the January 1989 meeting in Kauai. Since PCL is based on the metaobject protocol (or visa-versa :-)), most PCL-based CLOS implementations will include at least a varient of the same protocol. TI's implementation is not PCL-based, but it's (prime?) author was a member of the CLOS subcommittee. -- dan In real life: Dan Pierson, Encore Computer Corporation, Research UUCP: {talcott,linus,necis,decvax}!encore!pierson Internet: pierson@encore.com
