I'd advance two reasons against this idea: 1) It's more self-explanatory to explicitly call the appropriate converting method, enough with implicit madness! 2) For some operations, you'd have to know the types in advance before knowing what operations needs to be performed: $obj1 + 2; Now what __cast should be called? Int? Float? Also, what about $obj1 + $obj2: Int? Float? Array? Another example: str_replace($obj1, "bar", "foo"); what to call? __toString or __toArray? str_replace accepts both. IMHO it would only make sense to invoke methods on explicit casts only, otherwise it will just be a mess with PHP's current type juggling. But, as we seen with __toString, limiting the field of application was annoying (and it was later extended to nearly all string usages). So, what will it be?
