It's not just a different implementation, it's a completely different 
feature - there's no actual type checking at runtime, the type hint is 
more like an annotation for use with static analysis tools. See 
https://3v4l.org/ntCr7 which happily assigns int(6) to the "typed 
property" in HHVM, but is detected by the RFC branch.

(Incidentally, I note the TypeError's message is missing the variable 
name; I presume that's either a known issue or an out-of-date build on 
3v4l?)
