I, for one will really miss "the ! thing" when dealing with strings. It 
is much easier to adjust the end pointers to strings than it is to 
create a new string as a substring. Can we at least have that feature 
for 3.0, i.e., the ability to throw away beginning and ending character 
sequences. Forcing the programmer to manipulate strings will more than 
throw away any perceived time savings that you think you will be 
achieving by avoiding this case, not to mention making the programmer's 
job harder.
