Thanks for the pointer.

I never said it doesn't matter.

I brought it up because I'm curious. Because if it turns out that it 
actually is *difficult* to implement, that would be a point in my favour 
that *t doesn't naturally apply in list comps. And on the other hand, if 
it is *easy* to implement, that's a hint that perhaps I'm missing 
something and there is some natural interpretation of *t in a list comp 
that I've missed. Perhaps.

Just because I have a strong opinion doesn't mean I'm not willing to 
consider the possibility that I'm wrong.
