Both of those compile with dmd 2.060.

Really?  I'm using from-GitHub dmd, and with the above example I get a "cannot 
implicitly convert expression to immutable" error, e.g.:

    Error: cannot implicitly convert expression (testSets(nfRaw,0.1L)) of type 
TestData!(ulong,ulong) to immutable(TestData!(ulong,ulong))
