How to include block using machine name? I created a custom block that I want to include in my template file. But I don't want to include using block id. Is there any way to do it?

I enabled the box module so a machine name is added with each block. I want to add using machine name.
I dont think there are any machine names associated with a block. At least didnt saw it in the database. And by the way, why will you want to use the machine name when you already have an unique identifier like the "bid"/"delta" ??
