Its not that it doesn't work, but rather that it is not guaranteed to work, and the design is basically a pile of duck tape. For example, you can use Rust arrays in a C FFI declaration, but that won't do what you think it does: extern "C" { fn foo(x: [u8; 42]); } does not declare the C function void foo(uint8_t x[42]);
