Why would that be better than a simple typecast?  Typecasting to/from an 
object is a fast and easy way to associate an integer or enum with the 
strings in a TStrings object.  We know when we're doing this, and 
TStrings never does anything with the object, so the alternatives add 
runtime and code overhead that simply isn't needed.  Even if this was a 
one off thing I'd question introducing an object for it, but in our case 
there's literally dozens of spots where we use the technique with many 
different enumerated types.
