 One can use a global memory allocator to achieve indirection (`alloc::Box`, `alloc::Rc`, etc.), which requires using the nightly channel as of Rust v1.37.0, or one can use a statically allocated memory pool like [`heapless::Pool`].

 As this example of approach goes completely outside of RTIC resource model with shared and local the program would rely on the correctness of the memory allocator, in this case `heapless::pool`.
