Comment (by bgamari):

 I do wonder whether `collect_args` is being too conservative here: it will
 only look through ticks where `tickishPlace tickish == PlaceNonLam &&
 tickish `tickishScopesLike` SoftScope`. Even in the most restrictive tick
 placement type (`PlaceRuntime`) we allow ticks to be floated through type
 lambdas. Perhaps `collect_args` should continue to look through ticks, so
 long as there are no value-applications inside?
