As I remember from one of Abigail's bizarre sigs, ** is a 
typeglob as well as an operator.  And you forgot .. in the 
list of operators.  There's also ?? to go with //.

Commas, spaces, and newlines can be repeated as well.  Also, 
letters and digits can be repeated in barewords and numbers -- 
and regex modifiers can be repeated (though only /ee makes any 
difference).  Colons can be repeated in variable names, but 
probably not in any variable names that are usable for this.

Still hard to write a program in it, much less a JAPH.
