It works well enough to play around with Bluez, even interactively from the REPL, and it covers the entire C side of the Bluez API (yay for CFFI/C2FFI!).
The lispy helpers in
fancy.lisp may need some further extensions, but it should be mundane, not involving much extra complexity compared to what is already there.
For now it's little-endian only, but it's trivial to fix.
