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:

mixinbemto_block()+b.block-wrapper+b.block+b.elementblock+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 insidebemto_block mixin?
