For what's its worth (probably very little :-), I used a list of unbounded 
strings for that purpose in my Trash-Finder spam filter. If I was doing it 
today, I'd probably use an indefinite vector of type String instead (lets 
Ada handle memory management of the entire thing, not just the individual 
lines, and the overhead would be about the same). A bit clunky to change the 
length of a line (you have to use Replace_Element for that), but otherwise 
about the same as using an Unbounded_String.

(One of the reasons that the spam filter uses Unbounded_Strings was an 
experiment on my part to see how easy/hard it is writing exclusively with 
them. The experiment wasn't very successful.)

Yup.
