One question I'd like to ask first is: can anyone think of an alternative syntax that would make things clearer and remove the need for this kind of change? It seems like a Bad Thing if the .md files are now so indirect that people aren't sure what they're actually doing (and if mddump doesn't help or is needed so often that it's too cumbersome). Thanks, Richard
