Commands are executed one at a time, and errors are checked for each command;
if any command fails unexpectedly, no subsequent commands in the script are
executed. The command prefix ! indicates that the command on the rest of the
line (typically go or a matching predicate) must fail instead of succeeding.
The command prefix ? indicates that the command may or may not succeed, but the
