So the second half of the substitution counts as being sufficiently 
"inside" in order to grab the names from the first half?  Huh, I 
figured that would be a problem, since rules can be so heavily nested.  
Admittedly I haven't worked through it much, tho.

I've been under the impression that the following would _not_ work:

     $s ~~ /<number>/;
     print "I found $number";

but this does:

     $s ~~ /<number>/;
     print "I found $0{number}";

Right?
