Same error.

Sorry, I forgot to mention in that post that you have "toOffset" 
in your template constraint, which means it will also never 
match. You'll have to define it or replace it with `fieldName[0] 
- 'x';`

Also, you might not want to do `fieldName[0 .. 1]` because that's 
a slice (which is just another array of length 1). It won't do 
what you're expecting.
