Just listing the advantages of the withdrawn ircmaxwell's RFC
https://wiki.php.net/rfc/parameter_type_casting_hints over this one (both
v0.1 and v0.2):

1. No BC breaks (classes named int, float, string would not become reserved)
2. More semantic and explicit (just like S.A.N said)
3. Will not block possible strict typing RFCs to get voted in the future
4. No reserved words added
5. Minimalist implementation (no runtime flags, configurations, etc)

I'm not trying to highjack the topic here... just adding an alternative to
an RFC that seems to become more and more polemic with both sides
unsatisfied :)

Thomas,

Actually `(int)'asd'` would be evaluated to 0 ;) ... `(int)'1asd'` would be
evaluated to 1, though (I guess that's what you tried to say?).
