I understand that you could implement `writeln` in terms of `write`, but 
I question its practical value.   Why do you need to print a tree at 
compile time?  pragma(msg) and __ctfeWriteln are mainly for debugging, 
and adding a newline is very suitable (e.g. it won't mess up the error 
message in the next line).
