No, I'm not saying that. As I wrote in a previous message,

"In v2 we have a nice backtrace framework which can give you a call
stack backtrace with file names and line numbers."

However, for some kinds of errors it will be hard to for the system to
decide where the error actually occurred due to Jam's uniform syntax
and treatment of everything as a list-of-strings.
