Another instance of the *but you can roll it* argument ;-).
Certainly true, and creative, but misses one thing IMHO.
The index type of an Ada array induces the compiler
to test for correct index values.  Similarly, the compiler
will complain when a case distinction does not exactly
cover the whole set of values in a type.  Change the set of
values in a type and watch the Ada compiler tell you
which dependent declarations will now be incorrect,
or where a case value isn't handled by a case statement.

Suppose you could do the following in C. I trust that
C programmers would find this really cool:

#include <stdint.h>

enum Color {Red, Green, Blue};
typedef uint8_t rgb_intensity;

int main(void)
{
     rgb_intensity things[enum Color];  // This Here
     return 0;
}

a = http://itunes.apple.com/de/album/this-here/id218299914?i=218299916
listen(a[0]);

A := http://itunes.apple.com/de/album/this-here/id218299914?i=218299916
Listen(To => A(A'First));
