Protocol for avoiding pointers

@J-M-L

The [0] = {...} syntax is a C99 designated initializer feature, not supported in C++ until C++20 which is not what our compiler is.

GCC does support it in C++, but apparently only when the indices go 0,1,2,3,...

Testing with just [1] = ... :

moto.cpp:16:1: sorry, unimplemented: non-trivial designated initializers not supported
