I think that the overall consensus is that it's great but that
you do have to be careful about using it when it reduces
clarity without adding other benefits.

Using "auto" you can also have multiple return types.
auto foo(T)(T value)
{
static if (is(T == int)) return "int: " ~ to!string(value);
else return value;
}
You cannot give that function a specific return type as it's
either T or it's string. It's not a single type.
