Hi Emanuel,

Yes, this is how CL optional and keyword arguments work.  See (info 
"(cl) Argument Lists") and search for "SVAR".  It does require a bit 
more diligence in some cases, but it also provides more flexibility. 
And FWIW, I think I actually have to check the SVAR something like 1% of 
the time I use CL argument lists, or maybe less.  So that "gotcha" 
rarely "gets you" in practice.  :)
