I like this idea.  I had one similar last night, but you beat me to it ;)

My idea was going to be something that is similar to the current version 
statements:

version = _expression_ ? _identifier_ [ : _elseidentifier_ ]

Where the [...] is optional.

But your way looks cleaner.

Not in love with the version x = extern notation ...
