The API of BOOST_FUSION_ADAPT_ADT doesn't foresee this use, nor the unit tests do.
Because your snippet lies, it tells that it declare a Random Access Sequence, but yours cannot have the sequence elements modified.
But naturally this is your concern inside your app 👐. Because if you don't do any action modifying the elements you are not going to have any issue. It might happen when someone else will overtake your code without knowing you did that. 😄
But to your very specific question emptiness in parameters is not portable across compilers (sadly). Therefore you can avoid the warning and surprises in the future if you just provide any C++ expression doing nothing. You can use val
instead of /**/
. In the end the expression will be pasted into a setter function which will do only : val;
.
Hope this helps.

But Spirit's do and demonstrates it in an example.

Sadly this will confuse people looking at the code of the example.
Thanks for your answer.

Oups 🙊.
I could add a check to BOOST_PP_IS_EMPTY to handle this case. I'll give it a try today.

Huh, fusion have test with omitted arguments too
fusion/test/sequence/adapt_struct.cpp
Line 158 in f7b90f2
And produces bunch of warnings http://www.boost.org/development/tests/develop/output/teeks99-09-p-win2012R2-64on64-fusion-msvc-14-1-warnings.html#adapt_adt_named

I suspect it was here but had been removed in #124
