Which language are we talking here? Cpp? Because typeof hasn’t ever seemed useful to me in how I use cpp or how I have ever really used a language. I also remember it being criticized in java class more than 20 years ago when OOP was solely preached, even for scientific people like me.

I'm not shy about using typeof for logging when it's appropriate. Anything braver than that and you're probably getting into reflection, which also means you're probably not writing the code the way you should.

Hm, I’m currently working on a project with a ton of runtime-configurable plug-ins and dependencies between them. All of that is held together with a copious amount of black QMetaObject magic. I had the same thought about it, but I’m not sure how you’d get similar functionality without reflection and not making it even more convoluted and fragile…
