Did you insert an extra "doesn't" in that? If so, then I agree about
what isn't the core of the matter.

On the other hand, the snippet doesn't help without an
explanation. Especially with misleading comments.

Except temp *is* a reference. What it's not is a reference to
param['foo']. Instead, it's a reference to the same object that
param['foo'] is a reference to.
