[PD] array indirection

This probably fits into the category of a wish for PD; I think there's 
no way to do it currently, but I'd love to be proven wrong! 

I'd like to be able to change the data an array points to rather than 
actually change the data in the array.  The scenario which me think of 
this is, I'd like to have a display of a currently-selected waveform 
(which could be one of many pre-allocated arrays).  It would be 
wonderful to have a level of indirection where the display-array can be 
given a new address [object reference?] to one of the various 
pre-allocated arrays, after which it redraws itself.

I suppose this unleashes all the evils of pointers (multiple references 
to memory, etc.), but it would a serious advantage, performance-wise, 
for the scenario I'm envisioning.

I also think it would be very cool if arrays could act as buttons...but 
that's a different subject.
