To do it in almost-plain C, you'd need fairly complex macros that are more difficult to write correctly.
To do it in plain C without macros, or plain C++ without templates... you'd need to work out the combination of the template expansion yourself and write down a piece of code that is more likely to have bugs and more difficult to understand.
