An important purpose of a not bug-prone language is remove as many undefined situations as possible.
That's right.
If you add that to D2 specs, can the compiler catch at compile time all cases of violations to that rule?
Unlikely. But that has to be weighed against the former behavior being defined in a useless way.
D has something for the actions that must be done before the function exits, the scope(exit). Can something like that be used to automatically avoid undefined rounding situations?
Using an RAII object to do it might be better.
