Probably a stupid question, but what's a closure? (just point me to pod 
or whatever.)

And I was just going to think this would be beyond simple character 
substitution. Silly me. I assume this will work the same in UTF-16 
enabled Perl? 

Does Perl have a way to build a structure that would look in C like the 
following? (It defines the elements of a sort of sparse array.)

typedef struct translationElement_s
{    short lookNextLevel;
     unsigned char value;
     struct translationElement_s * nextLevel;     // next level 
translation array
} translationElement_s;

If so, is there a way to stuff such a table into an RE like the above?

At any rate, I have been assuming that all the talk about Perl supporting 
UNICODE refers to UTF-16, and I am wondering if anyone here knows what 
kind of preparation is in the works for taking Perl beyond UTF-16. 

Perhaps I should post this question to another list?
