Q: Constructing constrained/validated objects

DrucklesI'm trying to do some rudimentary DDD in validating my objects to ensure they are of a particular type.

@RubberDuck I VTC'd because it seemed to be asking for a rewrite/redesign using a completely different technique, as opposed to asking for a review of the existing code.

@t3chb0t I firmly disagree that the reason you mentioned on it's own is enough to justify a VTC.
@DerKommissar it's your right to think that and you've voted to reopen it. Water under the bridge.
@t3chb0t It is what it is. I just think there needs to be something else to warrant a VTC.
@DerKommissar it was enough for me; if it was always binary then bots could take care of that alone
I don't disagree at all
Generally these things are pretty gray, there's always going to be opinions one way or another.
