I wish we could use ``version`` as expression, to void the
repetition:
```D
import std.stdio;
enum HasTest = version (Test) ? true : false;
Tomek Sowiński wrote this template:
```d
enum bool isVersion(string ver) = !is(typeof({
mixin("version(" ~ ver ~ ") static assert(0);");
}));
static assert(isVersion!"assert");
static assert(!isVersion!"Broken");
```
I have something similar that i found somewhere here
```D
struct Version
{
static bool opDispatch(string identifier)()
{
mixin("
version(", identifier, ")
return true;
else
return false;
");
}
}
static if (Version.something == false)
{}
```
But i don't even use it since it requires me to import a module,
it not worth it, i'd rather have version as expression
