Question about improvement on reified generics

[Brian Goetz]

Thinking of Valhalla as being about "reification" is likely to take you 
down the wrong path.  We don't view erasure as a "bug" that needs to be 
"fixed" (despite how superficially attractive this sort of thinking is.)

The most likely place where we land is that value instantiations are 
specialized (so that the layout may be specialized), and reference 
instantiations will remain erased.  (All references have the same 
layout, so layout specialization is not needed.)
