>If you insist that all involved software components be in "the codebase," Where did I insist on that? Again, I could reuse ML modules just fine, as simple as I could reuse Objects. > Users, I said. Plugins, scripting, OS, etc. I'm a mirage OS user and I extend it quite fine, I could extend filesystems, block devices, write my own plugins to it. Why would I need OOP for plugins and scripting? Why can't I use modules instead? You don't need open recursion for extendability, a decent module system is fine enough. > call a function if it exists at runtime It's a very bad practice leading to calamities. A good half of Gstreamer bugs I've met were like that: use one function if it's defined or use another code path otherwise. This is exactly an explicitness I'm talking about, an obfuscated control flow, and I don't want to work with the codebase which employs that. Late binding could be easily emulated in Haskell/OCaml with environment (hashtable or map) of functions. People just don't do it because it is malicious.
