While reading "Embedding into a Program"
http://docs.racket-lang.org/inside/embedding.html
I see that the standard way of embedding Racket is via a dynamic library.
Reading up on iOS and dynamic libraries I notice that dynamic libraries
were not supported before iOS8 (on actual devices - I believe they work
in the simulator). Is it possible to embed Racket as a static library?
