thank you both for your answers! This renaming indeed provides a less
fiddly solution (somehow I did not think about using the simplifier on
Simpl programs ...).

Actually, this fails if the invariant needs to meta-quantified variables
-- I don't think we have a substitution variant of (rule_tac x=... in

It turns out that this is fairly easy to implement:

I've refined this now to a specialized tactic, so I can just write

  apply (anno_loop_tac my_named_loop="{...}").

Now this aspect feels quite natural.
