I think it depends. I have a quite opposite experience. I'm lazy and always
start to write a UNIX script. After a couple of hours fighting with that
mess I note (usually to late) that to write it in Ada (or even in ANSI C)
would take twice as short.

Yes.
All built-in string types should have a common ancestor.
Ada.Strings.Unbounded was and remains an ugly hack.

I'm using a table of tokens instead. The string is matched against the
table for a longest token that matches. And I always use anchored search. I
tend to do everything in one pass and Ada fits here well.
