Hi All there,


a similar suggestion to Rob Craig's attention since March, 12 2005
was related to the sequence manipulation, not so much important 
but that seemed to be nice in speeding some cases, refers to the 
Slicing of sequences. Perhaps to remind it can enforce the request.
 
An expression like:

newString­ =
originalString[1..2]&"INSERT"&originalString[5..9]&originalString[27..$]

could simply become:

newString­ = originalString[1..2]&"INSERT"&[5..9]&[27..$]

It should be plain to implement, I mean more useful than complicated...
