To my knowledge, no such syntax is supported by Guile's pattern matcher, which AFAIK is the one described in SRFI-204. https://srfi.schemers.org/srfi-204/srfi-204.html So your example is just binding the string "Printer" to the variable "..1": since "..1" doesn't have any special meaning, it's just a pattern variable. > (pk 'path path))) > > => ;;; (path "Bootloaders") > > Expected (and works with '...'): > ;;; (path "Bootloaders" "Printer") > --8<---------------cut here---------------end--------------->8--- > > and asking about it in #scheme or #guile, it seems the '..1' and '...' > patterns *must* be used strictly to match at the end of lists, ?? This is not what SRFI 204 says, and it's not consistent with syntax-rules and syntax-case patterns either.
