I used to maintain pdm4.

Colour me stupid, but I don't see why you can't have

    % biginit.hrl

    biginit(Arguments...) ->
       big,
       ugly,
       block.


    % main.erl
    ...
    -include('biginit.erl').

    main(...) ->
       biginit(...),
       rest of main.

OK, so it's *two* lines instead of one line, but is that a problem?

Failing that, what stops biginit being a single big ugly macro?
Again, at the point of use there would be two lines, not one.

I'm trying to think of anything I might want to include in the
body of a function that couldn't be in another function, and failing.
