C++ diaries...

I have to share to stay healthy ... I probably came across this one already but my brain just shuts off some times over this kind of well ... absurdity ... for the lack of a better word. :)

In C++:

namespace Whatever {
    enum SocketType {Stream, DGram, Raw};
    enum ProtocolType {IP, IPV6, Raw};
}

Will not compile and give you this: 

Error C2365	'Whatever::ProtocolType::Raw': redefinition; previous definition was 'enumerator'. 

Now a small search on SO gives:

"You cannot have equal names in old c-style enums. If you have C++11 - you can use enum class, static constants in classes, different namespaces, or you can simply use different names."

🤦

Looks like I have to use the new, third or fourth or fifth or ..., handle "from the water tap to not get sulfuric acid"*.

p.s: I was so amazed, I triple checked, it works properly in Ada.
