preconditions validate input to the method as a whole, while the proposed

Both of these have a

This contract system seems to be the best by far.

For me it's very simple, it's not obligatory use Type Hiting. Developpers
wants to write a weak code, they'll just have to not use Type Hiting and
developpers wants wrote a stric code they'll have to use it.

Just to add a little fuel to this fire, should we allow the specification of

type of functions, eg:
function int Factorial(int $num) {...}
What about things that return FALSE on error, eg fgets(), something like this:

hi,
I'm still in favour of #2 (Ilia's patch) as I don't see a real benefit

Hi!
According to Zeev's description of the behavior this would cause a

like that, but I think we need to devise a mechanism that allows you
to catch this error at runtime and write application logic around
it... In the
