Talk:IO Semantics

I don't understand in what sense this IO definition is a "semantics". Conal 04:49, 12 December 2008 (UTC)

It provides a concrete definition of IO that can be compared for equality to know if two IO programs are equivalent or not. --Roconnor 03:54, 3 December 2009 (UTC)

Maybe so. Thanks. For a semantics, I think I'd want a lot more equalities than the representation by itself provides, especially involving SysCallName.

Also (raising a new question), I don't see this semantic model at all addressing concurrency, which is a huge semantic complicator for imperative computation. Conal 08:13, 3 December 2009 (UTC)
