I think that would be quite stupid, as it would prevent users from
using shell variables in their commands, or multiple dollar-signs
for that matter. A completely unnecessary complication which would
only serve to limit Nagios' capabilities as a protection from a
completely harmless error caused by not RTFM'ing before typing.
While protecting users from making too many or too grave mistakes
is a fine thing indeed, it can be taken too far.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
