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------------------------------------------
