This would be correct if `i_am_a_feature` would be always defined, just
set to `false` if not existent. But I think the idea was to not define
the symbol at all if feature does not exists. In that case, the
condition should be `static if(is(typeof(i_am_a_feature)))`.
Yeah, you're right. It's different than ifdef.
I think version is the closest thing.
Note that you can convert versions into enums via:
version(define_the_thing)
{
enum the_thing_is_defined = 1;
}
else
{
enum the_thing_is_defined = 0;
}
