These instances were detected by searching for files that include IterationDecision.h, but don't match the regex: \\bIterationDecision(?!\.h>)\\b This is the only symbol defined by IterationDecision.h. In theory, one might use LibCPP to detect things like this automatically, but let's do this one step after another.
