Instead of a flat string, Erlang — oops, did I say Erlang? I meant Elixir — creates a nested list containing four leaf elements that add up to the string we expect: “Hello “, “&”, “amp;”, and " Goodbye”. At first glance this may seem like a pointless complication, but let’s see what the computer thinks about the situation.
If you look at the man page for writev, you’ll see it’s a “gathered write”, which means it writes data from multiple memory locations in a single system call. I wrote a little DTrace script to unpack the writev call we saw earlier, and peek at what that Elixir code is actually doing with this system call.

In order to allow concatenation of strings to be efficient in both time and space, it must be possible for the result to share much of the data structure with its arguments. This implies that fully manual storage management (e.g. based on explicit malloc/free) is impractical. (It can be argued that this is true even with conventional string representations. Manual storage management typically results in much needless string copying.) Though an explicitly reference counted implementation can be built, we will assume automatic garbage collection.
