A minimal example of mapping a native C structure to pony struct using FFI - Shows usage of Maybe, FFI and structs working together
// Use Pony struct's, FFI, and Maybe to map native structures to C
// Thanks to sclebsch for a little help with the embedded sa_data
// structure for which details are well hidden in sockaddr_in and sockaddr_in6
