I'm talking about type punning specifically here. There's a lot of old C code out there that stores everything in int * buffers and casts pointers back to the correct type. I'm even aware of one toolchain for a widely used MCU that typedef'd char to int (i16).
I believe this would be legal in Rust today if you respected the other rules, with the caveat that it wouldn't be remotely idiomatic or possible without unsafe.
