It is C++. I can use templates (although I would prefer to steer clear of it for the time being).
The problem is that I have written piece of code that dynamically loads shared libraries at run time (dlopen/dlclose/dlsym). Each module must have a unique ID and it needs to be checked for a correct value (!=0). I do this at load time as well, but it would be great if there was a way to do the checks at module compile time so people know of invalid ID's before the time of loading. For now, I have written a small preprocessor which is "checking" the module for correctness. Not the prettiest thing in the world, but it works.
