Missed beta reductions

[Simon Peyton Jones]

GHC always beta-reduces.

It does not always inline.   For that: -ddump-inlinings

What's the best way to find spots where GHC saw a redex and choose not to beta reduce? Is there a flag for that? It could be useful when trying to figure out why rules aren't firing.
