Wow, that does look interesting, and one file has over 16K LOC, when compared with the &lt;1.5K LOC of the OP&#x27;s Lispy C. Both seem to let you code in SEXPRs in a very C-looking style.
Others are raising Lisp to C solutions like ECL, but I have not really seen the C output of ECL, and you program ECL in Lisp. With C-Mera or Lispy C you are sort of writing in C with parentheses. At least that is how it looks to me. I have used Gambit-c and CHICKEN scheme before without really touching the C they output.
