toTrie, which is even simpler.


    import std.stdio;
    auto set = unicode("Number");
    auto trie = codepointSetTrie!(8, 5, 8)(set);
    writeln("Input code points to test:");
    foreach (line; stdin.byLine)
        int count=0;
        foreach (dchar ch; line)
            if (trie[ch])// is number
        writefln("Contains %d number code points.", count);

Alias CodepointSetTrie
