whisperity added a comment.
The problem with enums is that translating //zero// (0, 0.0, nullptr, etc...)
to the enum case is not always apparent. A warning **should** always be given.
And //if// you can find a zero member in the enum, we can report an automated
suggestion for that.
To give an example
enum class BaseColour { BLACK, RED, GREEN, BLUE, WHITE };
`BLACK` is the `0`, so we can fix-it. If the `0` is the first member (usually
in enums that have a well-defined "default" or "None" case...), then, it is
alright to use that as the automated fix.
However, if there isn't a "zero case" in the enum, for example:
enum class Something {
FOO = -2,
BAR, // This will be -1
BAZ = 84,
QUX // This will be 85
};
then simply using the first member might not be the best fitting action, so in
such case, I would opt for //no FixIt//. But, obviously, yes for giving a
warning.
