Comment:
You can get all kinds of compiler-generated stuff in a `-hd` profile,
because you're asking for closure descriptions. The description of a
thunk is the name of the thunk, which is often a compiler-generated name
since the expression did not have a name in the original program, or is
the result of inlining or transformation. You could use `-hc -hdsat_sugg`
for example to see what these closures were created by, or `-hy
-hdsat_sugg` to see what type they have.
BTW, is "critical" really appropriate for a profiling problem?
