I was looking for something like FirstOrDefault* from .NET in phobos. For example, I have this piece of code:

string findBobOrReturnNull(string[] names)
{
    auto r = names.find("bob");
    if(r.empty) return null;
    return r.front;
}

assert(findBobOrReturnNull(["alice", "bob"]) == "bob");
assert(findBobOrReturnNull(["alice"]) is null);

How can I turn that into something like this, or is there another idiomatic way to write it as a single expression?

string findBobOrReturnNull(string[] names)
{
    return names.find("bob").firstOrDefault;
}
