Walter and I just discussed the matter of inheriting constructors. Our
thought on the issue:
a) If a class doesn't define any constructors and adds no fields, inherit
constructors. Example:
class MyException : Exception {}
b) If a class defines at least one constructor, do not inherit
constructors.
c) If a class doesn't define any constructors but does add at least a
non-static field -> undecided.
What do you think?
I think c should be a compile-time error.
Why? (Not to be contentious.)
At first I thought you might want to add fields to a subclass for
logging, or caching, stuff like that, while still wanting to inherit the
constructors. Then I checked some code for a project I wrote in Java and
always when the subclass had new fields it defined a different
constructor, and the logging fields were static. So I think that most of
the time you'd want to inherit the constructors when you don't define
new fields.
