A few java enhancement suggestions

Question

I have just started using C# a bit after some years of heavy Java use. I am still a Java enthusiast, but a couple of features in C# I am finding very useful.
- "out" and "ref" method parameters. These are so much easier when dealing with multiple results instead of making temp result container classes.
- now that we have auto-boxing in 1.5, make arrays magically implement the List interface. I am finding it tremendously convenient to drop arrays where collections are wanted. Don't know how this interacts with generics/templates though.
Cheers,

Answer 1

out and ref parameters are hell. I don't miss it.
People who use it tend to end up with code very
difficult to maintain.With what language did you find out/ref args difficult to maintain?
I have found problems in C++/Delphi/Ada where one could not easily tell by reading source code calls that args were being modified.
However, C#'s simple solution: force the "out" and "ref" keywords in the call as well. Makes things clear.
I find myself getting tired of the tedious of creating little wrapper classes whenever I need to have multiple results.
Certainly if one abuses the feature there are problems, but having just discovered them again after using Java for so long, I am impressed by their usefulness.
