I do. The idea was to add type annotations to a snippet of code that 
could be helped a lot by translating them to C but doesn't inherently 
require it. For example John Maloney "prototyped" the sound prims, then 
threw in the required type annotations so we could translate them to C 
and speed them up by few orders of magnitude.

It does make sense if you think about the issue in the way that this is 
code with type annotations to make them translatable instead of thinking 
about them as primitives that can also be run directly.
