Just as Scott Meyers said: make it easy to use correctly and 
hard to use incorrectly. Today it's easy to use incorrectly.

While
  enum foo = [1,2,3];
  assert(foo is foo);
fails,
  enum bla = "123";
  assert(foo is foo);
passes.

Unfortunately after I found out the second one does not have to 
do with mutability. Making foo immutable(int)[] does not change 
anything. It only works for const(char)[], immutable(char)[], and 
probably w/dchar friends. That's odd.
