You could put the documentation in the module commentary of (sxml match), as texinfo. Or you could extend module-commentary somehow to look for commentaries in other sources. Probably easiest just to paste the texinfo you already wrote into the commentary, no? > The test suite reveals an interesting psyntax “problem”: renaming the > ‘xyzpq’ variable in sxml-match-tests.ss to ‘x’ leads to: > > ERROR: In procedure macroexpand: > ERROR: identifier out of context in subform `x' of `(quote (d (a 1 2 3) (a 4 > 5) (a 6 7 8) (a 9 10)))' > > Ideas? > > (Would be good if psyntax error reporting contained source location > info.) It would certainly be possible to maintain a stack of source locations in the expander, and modify syntax-violation to look in that stack. There is also the possibility of simply inspecting the syntax objects given to syntax-violation for source info, but it might not be there -- best to have a stack to at least give approximate info.
