   On the point about potentially incorporating symbolic shapes into Relay, I 
would like to hear more detail about how it can be done with Relay's system of 
accumulating type constraints and solving them simultaneously. If we were to 
handle dynamic shapes in Relay, we would need to define semantics for how shape 
variables are scoped and how assignments are handled, how they can be processed 
during the solving of type constraints, and what happens if symbolic shape 
expressions cannot be concluded to be the same at compile time. If this can be 
neatly incorporated into Relay, then it might make sense to pursue. I would be 
happy to brainstorm on that issue.
