i should have known this would happen. Day two of working with #commonmark-#java and I'm already writing an extension.
i *need* smart quotes & typography. only existing extension for it i found is in #Flexmark... which seems sadly to have fallen moribund, but it's also depending on features of its forked parser than the OG commonmark-java doesn't have. because you need contextual awareness. Seeing what I can do with SourceSpans but it might need to be a PostProcessor instead.
