So, is there any standard for Guile what error messages should I provide?

Are port-filename ,port-line ,port-column three enough?

And how about the format should I throw with them?

What about this:

------------------------------cut-------------------------------------------

(error "invalid syntax!" port-filename port-line port-column)

------------------------------end------------------------------------------
