In old EIEIO, the first argument to a constructor was a name.  I often 
used the name to distinguish between different instances.  That way when 
debugging I could identify which object instance was which.  Sometimes, 
such as above, there was no useful distinguishing name and a constant 
was used.

If I remember rightly, the name isn't part of CLOS, so it was made 
optional, and now appears to be obsoleted.  Since the only value of the 
name in most cases was for debugging, removing it should have no 
functional effect.

The one exception is if the class in question inherits from 
'eieio-named'.  I'm not really sure how that might be made to work 
without the name input, and I don't have a recent enough Emacs to easily 
see how it was adapted.

Hope this helps
