With people writing NIFs in Rust, how long until someone writes a new BEAM-compatible VM in Rust? The existing C implementation of the BEAM VM could be incrementally rewritten in Rust. I was browsing the BEAM source code recently and the C coding style is rather dated, e.g. lots of #ifdefs and even function declarations without prototypes.
