I would not think so.
1) There is nothing special with the value 0 in Ada. You can have (easily) types where value 0 does not belong to the type,
therefore 0 would not be better than any random value.
2) An uninitialized variable is a bug. This would help hiding bugs, not finding them.
3) Because of 2), there is already pragma Initialize_Scalars, which purposedly initializes all scalars to an *invalid* value (if
possible). Therefore, you'll get Constraint_Error during the first tests, not in production use. Much better.
