DESCRIPTION¶
Abort execution. If the current program execution was initiated by catch(E), that catch expression will return arg as error code, else the arg will printed as error message.
This is very similar to throw(E), but while throw(E) is intended to be called inside catch(E), raise_error(E) can be called anywhere. Furthermore, raise_error(E) includes the complete error handling with generation of a stack backtrace, making it a very expensive function.
