(byte-compile '(append '(1 2) '(3 4)))

(disassemble (byte-compile '(append '(1 2) '(3 4))))

resuts in

byte code:
  args: nil
0	constant  append
1	constant  (1 2)
2	constant  (3 4)
3	call	  2
4	return	  

Instead I expected it to be something like

byte code:
  args: nil
0	constant  1
1	constant  2
2	constant  3
3	constant  4
4	list4	  
5	return	  

I've never looked at byte-code optimization before, and I'm guessing
this is not a huge improvement, but I still wonder when all the
arguments of side-effect-free function are constants would it make sense
to calculate the result at compile time.

Thanks.
