After glancing through the haddock documentation and some googling, I can't tell if there's a supported way to link to a section heading in haddock documentation. Is there?

There are several things that could be of interest. - There is support for named anchors [1]. I guess this is your best bet for now. You could e.g. use "Foo#g:1" To link to the first section of module Foo. Disadvantages: (a) the id is not stable, it changes when you add new sections before that section (b) you can't decide on the link text, it is always the module name If it is ok for you to just link to some portion of text instead of the section heading, you can insert a named anchor (e.g. #foobar#) and use that (e.g. "Foo#foobar"). This solves (a), but not (b). - There is support for "named links [2]. This is already implemented, not sure when it will hit the road. - There is a ticket for exactly what you are asking for [3]. But no work has been done on that yet.
