[REBOL] Puzzle. Exists a not any-type! datatype?

The answer to this puzzle is "yes":
This is the proof, like a puzzle.
>From a console session (View 1.2.8):
object? o; == true
first o ;== [self a]
type? o/a ;== block!
length? o/a ;== 3 -- hu! it should be 2!
pick o/a 3 ;== -- mhhhh, unset?
unset? pick o/a 3; == false -- no? strange!
set/any 'a pick o/a 3
;** Script Error: set expected value argument of type: any-type
;** Near: set/any 'a pick o/a 3
; aaaarghhhhhhhhhhhhhhhhhh!!!!!!
length? append o/a 1 ;== 4 -- ok
pick o/a 4 ;== 1 -- ok again
set/any 'a pick o/a 3
;** Script Error: set expected value argument of type: any-type
;** Near: set/any 'a pick o/a 3
; aaaarghhhhhhhhhhhhhhhhhh!!!!!!
How to build the block o/a?
I think it is a Rebol bug, more than a feature.
