Here's what the internet says:

  According to the C++ standard, declaring a variable with the same name
  as a type is correct code in general, but invalid code within a class
  definition. The class case is specific, because names declared in a
  class definition are visible within the whole class definition, before
  and after the point of declaration of that name. In other scopes
  (global, namespace, function, ...) declared names are visible only
  after the point of declaration.
