That glue requires user intervention. Would you add "mixin(Reflect);" to 
every class you wrote? But even that isn't sufficient -- you would have 
to implement some interface indicating that this class has reflection 
information, and pass objects around via that interface rather than 
using Object.

There should be a way to suppress emitting complex reflection 
information -- a command-line flag and a pragma. But I think it's a bit 
much to ask users to mark every class they create in two different ways.
