  The snippit of code I presented in another thread [1] is a form of duck
typing.  I'm working on a socket framework (to handle both TCP and TLS
connections via Lua coroutines) and I'm mimicking the Lua file operations. 
Yes, I could create a FILE object from a TCP socket and use the normal Lua
functions, but that won't work for TLS.  So my own versions of read(),
write(), close(), etc).
