[REBOL] Bug of function error?

From: rotenca::telvia::it at: 22-Jul-2002 12:42

Can someone explain this to me?

a: "a" ; == "a"
b: tail a ;== ""
remove a;== ""
a ;== ""
b ;== ** Script Error: Out of range or past end
try [b] ;== ** Script Error: Out of range or past end

;until here all is OK, but then:

error? try [b] ; == false

Is it an error? bug?
