If you need the in-order capacity of tstringlist then you can use

http://www.stack.nl/~marcov/genlight.pas
 
- It is iterator based though, no array access to keys.
- Slower than most map solutions.
- faster than (ordered) tstringlist.
- Some tests indicate that the TStringlist slowdown is postponed from
   a few 100k to say 5M elements. (then you would need another level
   of indirection, though blocksize tweaking might buy you an order more)
- iirc duplicates are always ignores. I need to fix that proprely sometime
