version (xyz) unittest
{
    ...
}

is a good idiom. I noticed you feel strongly about bracing but I 
unrecommend it (and we should disallow it for phobos) as it forces you 
to either double-indent everything (net loss) or create an exception 
with regard to indentation. Also the opening extra brace has a "garden 
path sentence" liability, it suggests more stuff will be encompassed by 
the brace but then only at the closing brace there's the realization 
there's only encompassed entity.

The idiom is already used, see e.g. 
https://github.com/D-Programming-Language/phobos/blob/master/std/file.d#L322.
