Should inheritance (of non-interface types) be removed from programming languages?

Question

This is quite a controversial topic, and before you say \"no\", is it really, really needed?

I have been programming for about 10 years, and I can\'t honestly sa

Answer 1

Needed? No. You can write any program in C, for example, which doesn't have any sort of inheritance or objects. You could write it in assembly language, although it would be less portable. You could write it in a Turing machine and have it emulated. Somebody designed a computer language with exactly one instruction (something like subtract and branch if not zero), and you could write your program in that.

So, if you're going to ask if a given language feature is necessary (like inheritance, or objects, or recursion, or functions), the answer is no. (There are exceptions - you have to be able to loop and do things conditionally, although these need not be supported as explicit concepts in the language.)

Therefore, I find questions of this sort useless.

Questions like "When should we use inheritance" or "When shouldn't we" are a lot more useful.
