This method only does some special casing for our own helper class StringEnum, but not

for general enums. This is because:

|
|
* tg.constants currently only uses IntEnum as second enum type and json dumping that
|
|
|
|
is no problem
|
|
|
|
* if a user passes a custom enum, it's unlikely that we can actually properly handle it
|
|
|
|
even with some special casing.
