   That's wrong solution. Imagine I am writing a library (that includes the
"lower" function). This is  librry, so I cannot define "report_error"
function.
   Later you write few different interfaces to the library - web interface,
text interface (command line), curses, GUI... How can I call different
report_errors()?
   Exception handling solves this easily.

           Programmers don't die, they just GOSUB without RETURN.
