Presumably then exists() and the is_x() functions would be specified in terms of status() and lstatus() results. So in effect exists() and the is_x() functions are conveniences, very useful in many but not all cases, and safe to use casually since obscure errors will cause exceptions.
Sounds great to me!
I find it very odd for exists/is_* predicates to throw exceptions... and even odder for this to be described as "safe to use casually" when casual use may lead to aborting an operation when this is not desirable and the exception does not imply failure.
