Interesting.  "At ease" avoids the notion that "dismiss" raises
of the guard no longer being around.  It suggests that the guard
isn't paying attention.

Unfortunately, I don't think "at_ease" reads all that well in the
code.  One usually doesn't tell code to "take it easy" or "chill"
for a while, at least not in so many words.  It just sounds
strange to me.

So, if you choose to keep "dismiss," which really does seem like
a nice choice, what is a good antonym?  An interesting near
antonym is "muster:"

   scope_guard g;
   if (a) g.dismiss();
   ...
   if (b) g.muster();

A variation on "guard" (the verb) is "protect," which has the
right meaning and avoids overloading the word "guard" to excess:

   scope_guard g;
   if (a) g.dismiss();
   ...
   if (b) g.protect();

"Secure" is another choice.
