You could define something like this:
string x(string a, int n) {
import std.array;
auto app = appender!string(a);
while (--n) {
app.put(a);
}
return app.data;
}
void main() {
// prints "abcabcabc"
writeln("abc".x(3));
}
It's not as nice as "abc"*3, but unfortunately opBinary only works when
declared inside the class/struct; UFCS doesn't pick it up, so it doesn't
work on native types.
