It is not very intuitive to me that 2 == true returns true. Especially since echo true displays 1 on the screen.

I would rather see a boolean casted to an integer than an integer casted to a boolean during comparison, but this would probably cause compatibility issues. Failing that, perhaps if echoing a boolean value it should display either true or false instead of 0 or 1? Then you wouldn't be left thinking that these are integers at their core as they are in C.
