A repr() should in principle allow instantiation of the object. This would be a __str__. Also _type covers you more here.

As far as using the _type, I added an __str__ implementation that uses it.
I think having the full type path is useful in repr output which what is used in debuggers.
I updated the __repr__ implementation to use parenthesis instead of a column to be more compatible with the ability to pass eval
However, I feel that making it a 100% compatible with that (i.e. an eval(repr(metric)) that produces an identical object) will result in a string that will be too noisy and thus less useful when debugging.
