  Because it's often necessary to pass large slices and time is important.
eg, given
 Data : X(1 .. 50_000);
I can call
 Process_Middle(Rate, X(15_000 .. 35_000));
passing nothing just a pointer and bounds.  But if Rate and Data are part
of a record, I'd have to pass
 Process_Middle(X_Record'(Rate, X(15_000 .. 35_000)));
which I believe would require building a temporary object and copying
20K elements of X.
