Hi Arvids, I pretty much like this idea as it's more strict. Let me say something to the questions you pointed out here.

I'd like to handle it the same way as it's handled with the classes right now. If null is not the default-value you'll get an error when you pass null in there. One thing I'd like opened here: If you define a default-value different than null, should you be able to pass null as well and the compiler will use the default-value? > function a(bool $bool) {} > a(10); // Kill your self against the wall - write a(true); > If you define bool - use the damn bool! I like that. What should we do if this appears? As it's now - just throw an "Catchable fatal error" and let the script blow-up? I would go this far. > > I consider interchangeable only three cases: > 1. Numerical string. > 2. Integers and floats as strings. > 3.

All Boolean values are compatible be an integer (0 or 1) and all integer are compatible to a float and so on. Do you think it's good to have it this way? This would mean that you could also get a Boolean true as string "1" ... I personally don't like that ... but I don't know where to draw the strict-line. Now think about that backwards. Can a "1" be passed as a parameter that expects Boolean? If yes, I'd keep it consistent in both ways.
