@sgrif @tenderlove I get it. I just think we need to call it out more specifically, because I blew hours on it, and I know AR internals.

@erniemiller @tenderlove Definitely should call it out in the 4.2 docs, though. Wanna open a PR?

@sgrif @tenderlove Yeah, plan to — gimme a few — catching up on some stuff over here.

@sgrif One problem: can't find any solid docs yet on minimal API for a Type object. Not keen on recommending users subclass Type::Value

@sgrif …if only because it has precision/scale/limit and possibly other stuff that's not relevant for a domain object attribute

@sgrif It looks like it might just be cast/serialize/deserialize?

@sgrif Meh, scratch that. More involved than that. Suggestion: configuration of precision/scale/limit should be in a Numeric Value subclass

@erniemiller Strings, dates, and more also use those. The issue is avoiding `respond_to?` if it's used outside of the class.
