&gt; WebAssembly is Unix<p>The irony of this is that almost no UNIX offers a compelling, complete developer integration outside of things which produce slavishly detailed C-compat layers that introduce an ever growing number of undefined behaviors.<p>It also ignores that many lisp machines actually shipped with compilers for competitive languages. LispMs just had a lot of work (for the time done) on optimization for lisp environments. We take for granted the trivial execution overhead of interactive environments but this was no small feat back in the feat.
