It's rather strange that you are saying... Why would a few more empty
line at the end of a template file cause error? If the template
executes without error without those empty lines, then it will do with
the empty lines as well. I guess the error is caused by something
else.

BTW, it looks better to write: message = '"${d?string}"'

And, if you have empty lines after this, then d[x] is suddenly
undefined???
