Of course, an obvious reason: you really do not want to waste time comparing
pad characters!
The "=" defined in the GNAT bounded strings package of course does not
compare unused characters. So this inefficiency arises only if the
predefined equality is used.
One approach we were considering was a pragma
pragma Equality_Composes (type);
with the obvious meaning.
