See my reply to Mark citing
"[W]hat ES4 was planning on doing" needs to be qualified with "under
the default version" of JS, or under opt-in versioning. Again since
default versions get differing function statement semantics depending
on browser, unless all browsers can afford to break existing browser-
specific content, the change to unify on proposed ES4 semantics may
need to be under opt-in version selection only.
If some browsers implemented in a way that happens to work for most
browser-specific content (it's hard to be sure), then perhaps those
implementations could just make the change. But for cross-browser
portability, web scripts would want to select the explicit version
that guarantees the new semantics (and syntax, for that matter) in
all browsers that support that version.
