[PD] data-s with math inside (feature request?)

[Miller Puckette]

Hi all,

I'm working on haveing data struture templates 'catch' changes in fields
so that they can react any way they want. It's hard to figure out how
to make this efficient.  The "0.40" pre-release has some of this now, although
it isn't docvumented yet (messages appear on teh outlet of the 'struct' 
object when something gets cselected or dragged with the mouse...)

cheers
