if you don't mind, could we debate in WG2 the question that been
raised in this thread
https://srfi-email.schemers.org/srfi-159/msg/10433589?

The question is whether there is an incentive to modify SRFI 159 (aka
(scheme show)) so that — sloppily expressed — its state variables
become hygienic (so that SRFI's 159 promise in the abstract "... for
easily concatenating, composing and extending these formatters ..."
becomes true without exceptions).
