This has minimally better performance. Reported by me in #20228 (comment)

I am also thinking about renaming this to ConsumeEnumFlags to better reflect what it does, but maybe this can be done later or the existing name is fine already?

Concept ACK on both using ConsumeWeakEnum and renaming it ConsumeEnumFlags.

Better naming will be helpful for future generations of Bitcoin Core fuzzing enthusiasts, and ConsumeEnumFlags sure is a better name :)

I think the existent name "...weak...()" is good because the function may return a completely arbitrary value that is not in the enum. ConsumeEnumFlags() may give the wrong impression that it only returns enumerated values.

Though, "weak" could also be interpreted as "weakly typed enum", meaning a non-C++11-"strongly typed enum". But this interpretation would be wrong because flags can also be implemented with strongly typed enums. Maybe there is a better name that we haven't yet thought of?

On really verbose name could be ConsumeUnderlyingTypeEnum?

[09:35] <vasild> MarcoFalke: maybe ConsumeEnumOrRandom() better describes it?
