> AVR-GCC has C++ support

It's a very restricted subset of C++ that has almost no advantages over plain C, and some number of disadvantages.

[pjmlp]

- templates instead of macros

- constexpr instead of macros

- if constexpr instead of macros

- stronger type checking

- type inference

- strong type enumerations

- namespacing instead of pre-historic naming prefixes

- classes as means to enforce type invariants

I see some advantages.
