It says "hard to find a modern language that doesn't support the Sockets API". Ada does support the sockets API, of course, just like the others do. Pretty much the same way in all bindings. Let's see the well known "modern" languages of post 1990. Java, C#. Well, maybe the P* scripting languages, though these have roots/version inthe late 1980s. Will sockets APIs help with JVM or .NET? On the contrary: Ada -> JVM gives you the best sockets for the platform directly, *not* by having it added to the Ada standard, but by simply offering the JVM/.NET classes. Which aren't BSD style. > Although optional, even a so much few famous language as SML, ML. A language that got started in the 1970s. SML, being written in SML and C, got a binding to BSD internet sockets. A fairly thin interface if you look close. I mentioned extended attributes and no standardization at all because in this case 1) standardization work need not refer to any implementation; it can stay purely abstract. 2) virtually all standard file systems support EAs 3) virtually all archive formats support EAs 4) many programs make assumptions about EAs of files (such as the type of a file's contents) but lack Ada style explicitness. That' another standard that should live outside language definitions. While fewer modern OSs have support BSD sockets (remember, TCP/IP was an add-on to OS/2 and Windows, and to larger IBM computers, I believe), I thought that - if Ada was to standardize a binding, then that's new. Something standard that is not about an abstraction, but rather about including some historic incident like BSD sockets, in the language description. - it seems completely sufficient to agree, outside the standard, on an API that can be used with any Ada compiler. No standardization is needed at all. - Wait. We *do* have Ada Posix binding with an ISO number; since Posix sockets do the trick, there is no need to add them to Ada.
