Subject: Substrings by Position.

Hi,

   Just a logic question about substrings by position.

   foo = "012345678"
   foo[5,1] #-> "5"
   foo[-4,2] #-> "56"
   foo[-3,2] = "" #-> "0123458"

   Shouldn't a negative indexing work as well? (Below are just examples, 
they currently don't work) It will allow strings to be REVERSED easily, 
and thus doing something new.

   foo = "012345678"
   foo[-4,-2] #-> "43"
   foo[-3,-2] = "" #-> "0123678"
   foo[-4,-3] = "9" #-> "93678"
   foo[1,-2] = "123" #-> "3213678"
   foo = "01295678"
   foo[-4,-1] = "43" #-> "012345678"

   In other words,

   foo = "012345678"
   foo[4,1] #-> 4
   foo[4,-1] #-> 3

   Is this making sense?

Charlie
