If we allow "M.do" without explicitly importing M, building the module dependency graph suddenly requires parsing the entire module rather than just the preamble. How much of a concern is this for compilation times?

That would be a big deal for GHC, which currently relies on being able to parse just the header to determine the module dependency graph.

But nobody is suggesting this, right? Cheers, Joachim -- Joachim Breitner mail@joachim-breitner.de http://www.joachim-breitner.de/
