Thanks for the patch. I have committed a different version of it, which 
detects the absence of a lambda list and does not use LOOP (currently, 
the compiler is not so smart as to produce good code for the LOOP forms).

Well, I think the second form provides a lambda list (x y) with two 
required arguments, which is not compatible with the first one. The 
problem is that INSTALL-METHOD failed to detect this. I have fixed this 
also.
