Templating based on block/element names?

[kizu]

Is it possible to add a way to declare templates based on block/elements' names and modifiers?

Jade already have a way to call mixins using an interpolation:

+#{'b'}.block
  +#{'e'}.element

Would this be enough to allow defining custom templates, so things like this:

mixin bemto_block()
  +b.block-wrapper
    +b.block
      +b.element
        block

+b.block
  = "Whatever"

would be treated as:

+b.block-wrapper
  +b.block
    +b.element
      = "Whatever"

One of the problems is how to stop it being recursive, when the +b.block can be used inside bemto_block mixin?
