Why cmark is written in C?

Hi, I'm just curious. Why cmark is written in C instead of Haskell?

(A longer but more accurate question should be why write it in C and provide a Haskell binding and not the other way around?)

1. Speed.
2. Portability (easy to create bindings to a C library in
   any other language).
3. The current parsing algorithm is imperative in style;
   the C library gives a model that can easily be copied
   in other imperative languages.

That said, I'd be happy to see a pure Haskell CommonMark
parsing library.  If there were one, I'd use it in pandoc
instead of cmark.
