Is there a way to make a compile time check against the dmd/phobos version number? Functionally, what I'd like to achieve would be equivalent to:

    version(dmdVersion >= 2.070.1)
    {
        ....
    }
    else
    {
        ...
    }

I think I've seen something like this, probably using 'static if', but can't find it now. What I'm really trying to do is test for existence of a specific enhancement in phobos, if it's present, use it, otherwise don't. Testing for a particular phobos release number seems the obvious thing to do.

static if (__VERSION__ == 2072) { wow, it's dmd 2.072! }

Perfect, thank you!
