Hi Matthew,

My logic is that dynamic attributes are such different critters than 
regular args/return-values/labels attributes that they should be 
clearly marked syntactically as different.  I use the "what is 
a.b.c.d?" argument in Java as a case in point.  That could be any 
number of things.  We'll try it out this Summer and then back it out if 
everyone hates it. :)
