If you get collisions, it means you have something like struct X and enum X, which is stupid. Pick better names.
From a quick read-up: struct, union, and enum share a single namespace. So, struct X and enum X are not allowed in C.
Ah yes.
You can get conflicts by using the same name for functions and types:
struct X {};
void X() { }
int main() { X(); }
But (1) this is stupid, don't do it, and (2) the rules are clear that this disambiguates in favour of the function (for C compatibility) and if you need to refer to the type, you can still use 'struct X' to do so.
Requiring the struct tag in all programs, rather than just in stupid ones with ambiguous names, would not be an improvement. It would only benefit stupid code.
Though, I get the feeling that Liam guy is trolling us. He should just be using C if he thinks all these features are superior.
Yes, I was thinking the same thing.
