Hello,
I am trying to learn D and I have stumbled upon an issue
Consider this code:
```d
import std.stdio;
//version = Test;
int main() {
version (Test) {
writeln("Hello, world!");
}
return 0;
}
```
This compiles, however what if we want to turn the version
statement around?
I first expected `version (!Test)` to work, but it doesn't since
the grammar says:
```
VersionCondition:
version ( Identifier )
version ( unittest )
version ( assert )
```
We are using the first way, the one with the Identifier.
The reason inverting works with if-statements is because they
take an "Expression".
I see the way why it doesn't work, but I think it should.
Considering that
`version (Test) {} else {`
works without any issue but looks very ugly.
Can somebody explain if this is an intended decision or what I
should do instead of using my ugly replacement?
