I was looking at "Pure" https://en.wikipedia.org/wiki/Pure_(programming_language) out of curiosity or maybe a desire for an alternative to Tcl (small language, simple syntax, term rewriting, barewords, JIT, ...), then realized it's not in Homebrew (https://github.com/agraef/pure-lang/issues/34), and _then_ realized that it's basically completely dead and nonviable because it depends on LLVM features that were removed after LLVM 3.5 https://groups.google.com/g/pure-lang/c/nd__RPNI36I
