type annotation in keymirror doesn't get reprinted nicely, is syntax error #260

var keyMirror = function<T: {}>(obj: T): $ObjMapi<T, <K>(K) => K> {

gets reprinted as

var keyMirror = function<T: {}>(obj: T): $ObjMapi<T, <K>(: K) => K> {

which doesn't parse. This will need to be fixed in Babel or we'll need a different annotation here that re-prints.

Note: I shipped this in 0.8.13. I'm reverting that changeset and publishing 0.8.14 now.
