----------------
Well now, thanks for highlighting an inconsistency I did not know about. The documentation says that x[0] produces a list of the 0th element of x, which is why I suggested using !head. But that is true only in certain contexts, such as when x is a defvar. Otherwise it produces the single element. Ouch.
