If it's a sorting routine, then it probably sorts data in-place,
so it's more clear to not return data. If the function copies
inside the input data before sorting it, then it's right to
return the result.

Add 'static' to getAttribute and it will work. I know, it's weird, and
I've seen this sort of workaround used before. I think it's a compiler
bug.
I basically ended up doing what Jacob suggested.
To deal with the extra members from mixin Signal by using the compiles
trait to avoid the normal case for them.
Thanks for the help.
