Special functions and grammatical cases

I would like to force lower case with a function to a concept with an added grammatical case:

@lowercase(<#buyer: g>)

But it does not seem to work. Is there any other way to achieve this?

This is not yet possible with the current version of the software, but (together with the support for other languages) we are in the process of adding a special function to make this happen. We will probably name it @case, so that you can write @lowercase(@case(#buyer, "g")).

This new version should be released before, or very early, September 2021.

Perfect!
