Say I have a single object called Vector3, that allows nice things like

mag= Vector3->magnitude()
dot= Vector3->dotproduct(secondvector)

and so on. Then assume I've got a whole pile of vectors

pile= OBJARR(100)
FOR indx=0,99 DO pile[i]= Vector3

and want to manipulate them all at once

magpile= pile->magnitude()
% Object reference must be scalar in this context: PILE
% Execution halted at: $MAIN$

One foremost advantages of IDL is that logical groups of
vector and matrix operations can be carried out with a
single command. Am I correct in fearing that the only
way to get what I want is with something like this?

magpile= DBLARR(N_ELEMENTS(pile))
FOR indx=0,N_ELEMENTS(pile)-1 DO magpile[indx]=
pile[indx]->magnitude()

Any comments or suggestions would be most welcome.
