[Bug c++/33226] New: class name permitted in enum

[asteinarson at gmail dot com]

If an identifier given inside an enum is the same as an existing class
the compiler still accepts it:

<<< code <<<
class MyClass { };
MyClass g_my_class;  // An instance

enum { Mode1, MyClass };  // We could have error already here

MyClass g_my_class2;  // Compiler gives error here
<<< endcode <<<


For functions the desired behaviour is there:
<<< code <<<
int MyFunc() { return 0; }

enum { Mode1, MyFunc };  // Compiler objects here
<<< endcode <<<

Inside an enum it is very seldom the purpose to overwrite a class or template
in the global namespace. It is accidental, so an early error from the compiler
would be good.

Also template names can be overwritten inside enums.

I have to look this up but I think this code is valid.
