If you need to use x multiple times inside the if statement's true branch, you
end up having to declare a variable, e.g.:

if (foo in someAA)
{
    auto x = someAA[foo];
    someFunction(otherStuff, x, x, moreStuff);
}

As opposed to:

if (auto x = foo in someAA)
    someFunction(otherStuff, *x, *x, moreStuff);

I don't see why pointers are so bad. While, yes, D is a high-level language, it
is not C# or Java.
