It takes a special kind of stubbornness to reject the fact that version's limitations failed to serve their purpose.

IIRC the main rationale for version limitations is that they are supposed to prevent bugs related to preprocessors in other languages, which may be counter- intuitive to verify: People complain that it's not super friendly to combine versions but do they complain because of pernicious bugs inherent to the lack of combinations ?

side note: I'm not especially pro D-versions (my toy language allows version operator for example [1]), but I understand why they are limited in D. It's been explained many times.

Hi, thanks for trying the feature. I've created an issue[1] that can be referenced in the PR ;)
