-ddump-simpl will print out the complete, optimised
program. That'll tell you what's been inlined.
-funfolding-use-thresholdN changes the inlining threshold
Default for N is 8
-funfolding-keeness-factorM.N changes how heavily GHC weights
'context information' when deciding to inline. Default is 2.0.
Bigger numbers mean that a favourable context has a bigger effect.
