>  A reference is as flexible as a C pointer or C++ reference.

In what ways ? I don't think we should compare references with C pointers. It's confusing for the new comers (assuming they are the targeted audience).

Also:

> the core concepts will be familiar to anyone who has worked with C or C++

afaik the community is not interested in the dynamic languages new comers, should we really exclude them this bad ?

What's your opinion ?
