Yes, I think this is a dead end: glibc could well end up become on
Haskell (hi, Pandoc!), and then the whole module split effort collapses.

Ultimately, I think we need to look into optimizing the compiler.  The
profiling I did a while back¹ suggests pessimal behavior of some of the
compiler phases when given large inputs.

  (I’ve been meaning to resume that investigation for a long time, but
  I’d really need to do nothing but that for a couple of weeks…)
