For clarity, what are the bad connotations of template wrt C++?
I never wrote a useful line of C++, but I used to hear templates described as "too complex for most people to understand" and Scala's generics described as a "sane version of templates". I've no idea how true any of that is, though.
Got it. I think to get utter generality out of either requires knowing subtle details, but the specific difficulties are different for each case. Greater control is baked into generics use than templates use.
I think that's mostly because of the advanced template meta programming features that come with it. Mind you, template meta programming is turing complete. Imagine the "fun" stuff you can do with only templates in C++.
Did some templates in C++ for undergraduate (2005-6) They were just a pre-processor mechanism, to copy-paste code and substitute. Some syntax, but no type-checking. Only upon application you would get it. Not like Java generics. Understandable, since it precedes those.
