Cのマクロを使えばこんな書き方だって出来る
#define ABCD_LUMP_OPERATOR(OPERATOR,VALUE) a OPERATOR VALUE; b OPERATOR VALUE; c OPERATOR VALUE; d OPERATOR VALUE;
ABCD_LUMP_OPERATOR(+=, 5)
hoge_func();
ABCD_LUMP_OPERATOR(++,)
#define ABCD_LUMP_OPERATOR(OPERATOR,VALUE) a OPERATOR VALUE; b OPERATOR VALUE; c OPERATOR VALUE; d OPERATOR VALUE;
ABCD_LUMP_OPERATOR(+=, 5)
hoge_func();
ABCD_LUMP_OPERATOR(++,)
