go语言以下代码转换成d语言版本func reverses string string runes = runes for i j = 0 lenrunes-1; i j; i j = i+1 j-1 runesi runesj = runesj runesi return stringrunes

import std.utf;

string reverse(string s) { dchar[] runes = s.toUTF32Array(); for (size_t i = 0, j = runes.length-1; i < j; i++, j--) { swap(runes[i], runes[j]); } return runes.toUTF8String(); }
