How about changing the method signature into `def getSimpleName(obj:
AnyRef)`?
Then, we simply handle two cases; one is correct and the other
non-correct?, e.g.,
```
def getSimpleName(obj: AnyRef): String = {
if (incorrect case) {
// Canonicalizes the name for correction
...
} else {
// If no problem, just returns getSimplename
obj.getClass.getSimpleName
}
}
```
