Maybe it fit?

auto stringB = readln.chomp.map!(to!dchar).array;
auto stringC = readln.chomp.map!(to!dchar).array;

auto charAppender = appender!(dchar[][]);

auto totalStr = stringB.repeat(3).chain(stringC.repeat(5));

charAppender.put(totalStr);

writeln(charAppender);

charAppender.put("c"d.dup);
charAppender.put("test"d.dup);

writeln(charAppender);
