Object properties in echo()

[JS Bangs]

I started using PHP's object-oriented stuff a little while ago, which has
mostly been a joy. However, I've noticed that they don't seem to echo as I
would like. Eg:

$this->field['id'] = 255;
$this->key = 'id';
echo "$this->key is $this->field[$this->key]"; // prints "id is Array[id]"

// Thus I am forced to do this
$keyval = $this->field[$this->key];
echo "this->key is $keyval"; // prints "id is 255"
echo "this->key is " . $this->field[$this->key]; // also works

This example is trivial, but it becomes much more of a nuisance when I'm
making forms and whatnot and don't want to have to define a whole bunch of
new variables or keep opening and closing quotes. Is there a workaround or
different syntax I can use for this, or am I just stuck?

Jesus asked them, "Who do you say that I am?"

And they answered, "You are the eschatological manifestation of the ground
of our being, the kerygma in which we find the ultimate meaning of our
interpersonal relationship."

And Jesus said, "What?"

Yeah, enclose them in {}, e.g.:
"{$this->key} is {$this->field[$this->key]}";
