Long version: My code was evaluating happily yesterday (on what much have been an old version of Emacs) but came up with that error on 27.1 today.=C2=A0 It turne= d out I had "(, " in a few places. They should have been "(* ", (OCR failure) so I suppose I should thank the error message for helping me find those... but it's a confusing message when source doesn't contain any backquotes! (I spent a while Googling to find out what was happening but only found cases of people getting the error message whose code *did* contain a backquote.)
