For example i have in scriptA.gd class:

class Effect:
    var name: String
    var stat: String
    var value
    
    func _init(name: String, stat: String, value) -> void:
        self.name = name
        self.stat = stat
        self.value = value

And i want to reuse this class in scriptB.gd without just rewriting it in scriptB.gd
