If you want a bit more advanced looping you could have a look at my goof-loop:
https://git.sr.ht/~bjoli/goof-loop
It currently does not support a break or continue clause, but adding one should
not really be a problem.
A good thing is that it does not rely on mutation for anything except higher
order sequences, meaning it does not lead to the implicit boxing overhead of
set!, which is a good idea in loops since that quickly adds up.
Best regards

I also have a mutation-free loop macro, named 'hat-let' or 'let^':
https://git.gnunet.org/gnunet-scheme.git/tree/gnu/gnunet/utils/hat-let.scm
Its origin is rather different though, goof-loop appears to be the
result of combining various loop-related constructs, plus some extras,
whereas let^ is the result of combining various binding constructs
(including the 'let loop'), plus some extras.
It combines the following: let*, lambda / define, receive, 'let loop',
'if', 'begin'.
Doesn't do any accumulation though.
Greetings,
Maxime.
