Honestly, reading that snippet … suggests to me that make-parser might not actually be useful without all of the other internal ssax functions, and that perhaps make-parser really shouldn’t be exported, after all :). Is it possible to formulate productive uses of make-parser that don’t require a bunch of other functions in the ssax module?
Alternatively, perhaps we can come up with good documentation for a whole suite of useful functions, and expose them all? John > On May 16, 2018, at 11:57 PM, N.
