I don't agree.  I think putting To_Bounded_String all over the place
makes the code *less* readable.  Bounded_String is, conceptually, a
string type (even though the RM doesn't say so), so string literals
ought to be allowed for it.

Using varying-length strings should be just as painless as using
Standard.String; literals, array indexing, etc, should be allowed
without cluttering the code with explicit conversion operations that
don't really do anything interesting.

Well, we don't know why the OP wants same-length strings, but I agree --
such a restriction seems suspicious.
