Since Ruby doesn't care what you use as delimiters, usually...

   >> %q delimited_with_spaces .inspect.display
   "delimited_with_spaces"=>nil
   >> %q      delimited with plain 'ol tabs   .inspect.display
   "delimited with plain 'ol tabs"=>nil
   >> %q
   ?> and with newlines?!?
   ?> .inspect.display
   "and with newlines?!?"=>nil
   >>%q^Hbackspaces are stranger yet^H.inspect.display
   "backspaces are stranger yet"=>nil
   >>%q^CBut the interrupt character really takes the

   "But the interrupt character really takes the cake"=>nil

I beg you, though -- *please* don't take advantage of the fact that you 
can delimit strings with interrupts!!! ;)
