+/**
+ * Return a CommandResult as the result of a command to pass both an exit
+ * code and result data from a command.
+ *
+ * Usage:
+ *
+ *      return CommandResult::dataWithExitCode(new RowsOfFields($rows), 1);
+ *
+ * The CommandResult can also be used to unambiguously return just
+ * an exit code or just output data.
+ *
+ * Exit code only:
+ *
+ *      return CommandResult::dataWithExitCode(1);
+ *
+ * Data only:
+ *
+ *      return CommandResult::data(new RowsOfFields($rows));
+ *
+ * Historically, it has always been possible to return an integer to indicate
+ * that the result is an exit code, and other return types (typically array
+ * / ArrayObjects) indicating actual data with an implicit exit code of 0.
+ * Using a CommandResult is preferred, though, as it allows the result of the
+ * function to be unambiguously specified without type-based interpretation.
+ *
