I'm curious, is your reason for this purely to avoid allocations during 
lexing, or are there other reasons too?

If it's mainly to avoid allocations during lexing then, maybe I've 
understood wrong, but isn't D2 getting the ability to construct class 
objects in-place into pre-allocated memory? (or already has the ability?) If 
so, do you think just creating the tokens that way would likely be close 
enough?
