slime が時々通信に失敗して mode-line に数字が出たままになる。 slime-reset すると直るが・・

ssh経由で slime が hang する件のメモ
;; 接続が失われた後で slime-auto-select-connection を拒否すると以下が出る。
Warning (slime): Caught error during fontification while searching for forms
that are suppressed by reader-conditionals. The error was: (error "No default connection selected.").

最速 fizzbuzz に sendfile や tee を使おうと思ったけど、端末にはどちらも使えず pipe で cat とかに繋ぐ必要があって残念
#include <stdio.h>
#include <stdlib.h>
void __attribute__((noinline)) fizzbuzz_basic (void){
int i;
for (i = 1; i <= 100; ++i) {
if (i % 15 == 0) {
printf("FizzBuzz\n");
} else if (i % 3 == 0) {
printf("Fizz\n");

with-c-syntax backquote
* #{ -> ` -> #{ をネストできるように
* flet や handler-case や with-open-file で遊ぶと nest の例できそう
* struct 対応
* vacietis に触れる
