It would seem better to say: sloppy mode === no block scoped > function declarations. strict mode === block scoped function declarations. We don’t want to leave the meaning of function declarations in blocks completely unspecified, as in ES1-5 as we; know there are legacy compatibility requirements for them. So, we need to have some semantics for them. The easiest way to provide any semantics is to simply use the same block scoping semantics that is used in strict mode (slight augmented to over the legacy intersection semantics). That actually limits the refactoring hazard because as long as you have no code that depends upon the legacy intersection there is no difference between the function in block strict and sloppy semantics.
