define enum class with same name compared to enum [duplicate]

Question

Why this compiles in c++11:

struct foo
{
  enum class Resolution { None=10, Nominal=20 };
  enum class Scale { None, Nominal };
};

while this doesn't:

struct foo
{
  enum Resolution { None=10, Nominal=20 };
  enum Scale { None, Nominal };
};

?

You don't need to put it inside of a struct to produce this ambiguity. — stefan

Before C++11 enum values were unscoped, meaning, that values in 2 enums can't be same. This is no longer the case when using enum class.
