I will add a comment:

# The test selector starting with a hash (#testid) will be stripped by all evals
# and will be reinserted in the last line by calling TestID (if it is present).


Arguably I should also remove the hash part explicitly, would you like that? I 
think it might be more clear what the code does, but on the other hand it would 
maybe signal that it is a parsing strategy which it is not.
