Functions that return Error return OK when no error occurred. Most functions don't return errors and/or just print errors to STDOUT. Methods that return [enum Error] return [constant OK] when no error occurred. Note that many functions don't return an error code but will print error messages to stdout.
Since [constant OK] has value 0, and all other failure codes are positive integers, it can also be used in boolean checks, e.g.:
[codeblock]
var err = method_that_returns_error()
if (err != OK):
print("Failure!)
# Or, equivalent:
if (err):
print("Still failing!)
