I think everybody agrees with you on that last point (and perhaps similarly for 'virtual', though changing that to 'nonvirtual' would violate the 'you don't pay for what you don't use' principle, so perhaps not), but such is the backward-compatibility burden...

Not sure I feel the same about virtual because of the "only pay for what you use" principle. Another thing: something like a 'delayed const' (similar to 'final' in Java IINM) so that you can modify a variable and then 'constify' it so that it doesn't change after that point (something the compiler could enforce rather than assignment to a const& and relying on people to not use the pre-const& variable after).

The 'delayed const' sounds like a finer-grained 'mutable'.
(But don't mention Java. Java's lack of constness is *awful*. More than once I have introduced horrible bugs because I accidentally modified a hash key due to the silent aliasing and lack of const of java.util.Map -- meanwhile such bugs never ever happen in the STL, not due to its nifty space-age genericity, but simply because its data structures copy the types handed into them, and won't give you something back that shouldn't be modified without a const on it. For that matter I have written data structures in poor old crude C with the same 'always copy, use const' rules as the STL, and *they* never suffered from this either.)

Yes, that's one of the very few features that I truly miss in Java. There are workarounds like defensive copies and immutable wrappers but they're no fun.

Also typedefs. I hated using Strings for everything and 5 parameters all of String to Android APIs means having to look up what the order is. At least the ordering is consistent where I used it (unlike, e.g., PHP)
