The same issue came up with 'version' recently. It is possible to start
a
version block like this:
version(something):
However, it is not possible to get to the "else" part of that version

using the above syntax. Would the same syntax work for version as well?
version(something):
// ...
!version(something):

Yes, this has come up before, in various forms. The short answer is
unequivocably "no". I've expounded on this extensively in this n.g., but
don't have a reference handy.
Negating version is not the main problem, as one can do version(x){}
else{}, which is ugly but effective.
Logical AND is also quite easy with version(x) version(y) {}
The one I would really like to see is logical OR. There is no easy way
around this, one must come up with convoluted mechanisms that are much
harder to design, write, and understand than just version(x || y)
