Library gap aside, Lisp has an FFI. If you want to use libpng from Lisp, you just make some C calls. If you want to use libpng from Hoon, you first have to re-implement the functionality of interest in Hoon just to have a sound basis for using the C library (as a drop-in optimization, or "jet").

This obviously makes for slower going, especially near the beginning.
