The test using \removepunctuation that you provided does what it should be
doing (it produces 6 instances of "test-test" with the intervening
punctuation mark in each case removed), but it doesn't do what I'm trying
to do in the MWE above. I'm trying to take certain punctuation marks that
follow the \autopuncttest macro and place them before it instead. Looking
at the typo-chr .lua and .mkiv files, I see that there are \pushpunctuation
and \poppunctuation methods in addition to the \removepunctuation method.
These might be useful for this purpose, but in any case, I still have to
check if the trailing character is one of the characters in a specified
set/string, and this is where the error is arising.
