Thank you, but this one doesn't seem to handle tables:

$ make
a=bpack({hello="world"},"Ab8","\027Lua",5*16+1,0,1,4,4,4,8,0)
test.lua:11: bad argument #1 to 'bpack' (string expected, got table)

Sorry, I did not mention tables (and recursion) exeplicitely, although
I meant to imply this by cyclic references.

Also I would have problems with reliance on binary data representation
between different Lua versions and architectures. This doesn't rule out
a solution entirely for now, but in the medium to long term.

Addendum to the requirements list:
- Must handle tables recursively

- Timm
