I agree that unchecked_conversion isn't evil. Nor are the other unchecked
services provided by the language. In fact, the very way they are provided
supports the notion of Ada's default of "safe" while permitting a designer
to relax that default when necessary.
The default access parameters is "unsafe". I am simply suggesting that a
constant designation in the parameter list would ensure a safer implementation,
and it would tip off the client of a function that the parameter in would never
be altered in any way.
