I believe the suggestion was not to add hyperlinks automatically, but
rather to *remove* them automatically. For example, with such automation
I can just write 'Int', 'Foo', or 'Local.Bar' everywhere and leave it up
to Haddock to ensure properties like only the first one actually being a
One reason this would be beneficial is that it means we wouldn't have to
stop and think about whether a given identifier has already been linked
for this page, let alone maintain the firstness quality when we decide
to rearrange the order in which things occur. Automating things like
firstness is the only reliable way to be consistent about it, just like
when giving citations in papers (e.g., many LaTeX packages will Do The
Another benefit is that there is often debate about stylistic
differences like this, and so it makes sense not to hardcode that into
the documentation itself, but rather to let you change the style easily
by altering the flags you pass to haddock. When LaTeXing I do this sort
of thing often, by using semantically oriented macros whose definition
can be easily swapped out in header files according to the whims of
different journals. One of the main problems of JavaDoc, IMO, is the
focus on an operational kind of markup instead of a semantic markup that
actually captures what you mean.
Assuming I've read Ganesh Sittampalam's suggestion accurately, I'm all
for this. I may even have some time to offer once classes are out.
