Bash is treating ! as the history substitution character, and either
erroring out or substituting a previous command line. ^ has related

... dies with an identical message
??? produces the message, but continues operating.
The only difference I can find between !!! and ... is that !!!

it needs to be callable (say, a debugging function).
Given the difference in
