<div>Does the role of contract checker act something like validator? If so, does that imply binary_to_term/ term_to_binary does not use that because the communication happens within Erlang environment? I could totally go wrong as I am not familiar with it; but I am curious, because I learned a lot of concepts from Erlang and from reading Joe Armstrong's thesis, even though I never wrote any Erlang code at all. Really appreciate those writings. That helps me a lot in learning system design, and many other parts in programming as well. <br></div><div dir="auto"><br></div><div>Oct 28, 2021, 21:51 by <a href="mailto:ulf@wiger.net" rel="noreferrer" target="_blank">ulf@wiger.net</a>:<br></div><blockquote style="border-left:1px solid rgb(147,163,184);padding-left:10px;margin-left:5px"><div dir="ltr"><div><br></div><div>The key feature of UBF was that beyond being a serialization format, it was also a contract checker.<br></div><div>That was a very nice feature.
