be creative! ;-)

  import std.algorithm, std.stdio;

  void main () {
    string s = "he is at plane";
    if (findAmong!((string a, string b) => b.canFind(a))([s], ["home", "office", "sea", "plane"]).length) {
      writeln("got it!");
    } else {
      writeln("alas...");
    }
  }

or:

  import std.algorithm, std.stdio;

  void main () {
    string s = "he is at home";
    if (["home", "office", "sea", "plane"].canFind!((a, string b) => b.canFind(a))(s)) {
      writeln("got it!");
    } else {
      writeln("alas...");
    }
  }
