How would you write "once" routines in C++?
How about the fine grained visibility control (where each feature
can be made visible to only a specified set of types)?

They are different I think. Can you express
deferred class C [P -> T]
feature foo(x: P): P is deferred end
end -- C
in C++?
Then there is currently a (justified) limitation in C++ with
float parameters. This is not the case in Ada generics.
