How "Blueprintable" make a class blueprintable?
According to UE4 class specifiers, "Blueprintable" can expose a C++ class to be base class of blueprint class. I'm confused in how this works?

Unreal Header Tool parses the "Blueprintable" metadata in the UCLASS macro and expands it to both "IsBlueprintBase" and "BlueprintType".
In the editor, FKismetEditorUtilities::CanCreateBlueprintOfClass(const UClass* Class) checks the existence of the "IsBlueprintBase" (FBlueprintMetadata::MD_IsBlueprintBase) metadata on the UClass as one of the possible methods of determining if a class can be a base class for a blueprint.
