DMD 2.094.2 fails with the same error?
But current master works for me.

That's a bug, ordering of import should never affect whether some 
code compiles or not.

The ordering of imports can make a difference in some cases 
because it affects the order in which dmd analyses declarations - 
which might hide or reveal a bug.
