I don't think you understand the issue. It's the same mixin but 
with different parameters for the generation, thus this is not 
possible, because you don't know which one of the exact generated 
ones is the issue,

Like I also said this does not apply to normal mixins but usually 
very big mixins composited of multiple mixins and template mixins.
