Not the parent, but `auto` in c++ improves the situation wrt implicit conversions as variables now automatically get the type of the thing assigned to them. IOW: less unintentional implicit conversions.

'auto' is only available to use when the type of a variable can be automatically deduced from its initializer, meaning the declaration would be redundant. It has nothing to do with type conversions.

edit: now I see what you mean in the context of adding assertions to make type conversions safer, and how there could be some parallels with auto for that
