           Summary: rename the variable "degrees" in sumtype.d at least in
                    the kelvin case

```d
    struct Fahrenheit { double degrees; }
    struct Celsius { double degrees; }
    struct Kelvin { double degrees; }
```

According to WP there is no "degree Kelvin" ("°K") [1]. I would like to suggest
renaming "degrees" to "temperature" or "value". The "°" has been dropped 56
(fifty-six) years ago [2]. Also note that the name of the unit is "kelvin" (all
lower case).
