Why does not Ada support variable function/procedure argument lists? Is it hard to implement or does it somehow go against "we should keep things secure" philosophy of the language?
Varargs were over there at least as early as C and allow very handy things like printf, the likes of which can also be found in other languages like Java or C#. Another neat example is logging functions where it is usual to pass information from all kinds of data types, not only strings, in separate arguments.
And even if this is considered non-secure technique, Ada could still make it better than at least in C by e.g. throwing an exception if there is some mismatch between format string and the actually passed arguments.
