Haddock comments on enum constructors

Haddock comments in `#fun` commands are passed on to the generated file, so that imported function arguments can be documented. Is it possible to do the same for imported `enum`s?

For example, if the C header file `foo.h` is
```
enum MyEnum{ FOO = 1, BAR = 2 };
```
and the CHS file is
```
#include "foo.h"

{# enum MyEnum
as MyEnum
{ FOO as Foo -- ^ foo
, BAR as Bar -- ^ bar
}
#}
```
then the generated hs file defines MyEnum as
```
data MyEnum = Foo
| Bar
```
The haddock comments have disappeared. Is it possible to maintain them during generation, so the generated file contains
```
data MyEnum = Foo -- ^ foo
| Bar -- ^ bar
```
