Yes except that it seems to be more core to C# than to Java (or python): https://msdn.microsoft.com/en-us/library/s1ax56ch.aspx And then this distinction goes all the way down to the CLR [in ways that I am not very clear about] eg http://www.informit.com/articles/article.aspx?p=30608&seqNum=3 > Apart from the possible efficiency gains, what benefit do you see from > distinguishing between "values which are objects" versus "values which are > not objects"? As I said, in the context of a low level language its probably a bit of a misnomer However conceptually/pedagogically making a fundamenal distinction of timeless | time value | object immutable | mutable expression | statement function | procedure is key to getting programming [and is something that Pascal got better than most of its successors]. The FPers want to squeeze the whole world into column 1 The OOPers want to do the opposite and are embarrassed by the existence of column-1 [status of int in java etc] Unless one is committed to some philosophical extreme position -- Only One True Way -- I believe accepting two fundamentals is the most sane choice
