All I'm saying is that is what the error message is saying "you're trying  
to mixin something that's not a string.  It needs to be string"

Other than that, I'm not sure how to make dwin or juno work with a proper  
string type.

Not sure either, but empty called on a string should be evaluatable at  
compile time.  You should file a bug with a minimal example.
