what is the alternative to object-orientation?
A long time ago I went to school for computer science and I remember a big push towards functional programming at the time.
I saw a little bit of Scheme and logic programming and I thought it was neat. I can appreciate those different ways of writing code, but I'm still not sure how any of those other styles actually replace object-orientation. I've started to look at Scheme again and I'm noticing that textbooks and libraries will actually build an object-oriented system on top of Scheme using macros. That has pedagogical value, but it seems like we're back at square one?
If you look at chapter 2 in SICP, one of the topics they cover is message passing. They don't use an explicit object-oriented system. Instead, they have an inner dispatch function that operates on local/private data. That seems like the behavior that classes are trying to model in other languages.
Getting to the point... my feeling is this: bundling state and functions seems like a basic thing in programming. This behavior seems to emerge even in systems which don't explicitly call themselves object-oriented. So my question is this: is there a real alternative? Are there large software systems which don't recreate the behavior of classes?
