Comment (by simonpj):

 Sadly, the lint error is a bug in lint.  In the conversion from Core to
 STG we replace `(Coercion blah)` with `coercionToken#`; the latter has a
 fixed type.  It's just a placeholder.

 STG lint complains about this but it shouldn't; we could have recorded the
 type in `corecionToken#` (maybe by having variants or something) but it'd
 just be work to no gain.

 So I am sill clueless about why this `stg_app_ppp` thing is happening,
 sorry.
