Header-limited scope is hard to define. Do you mean expression-local? (Also hard to define.) Do you mean local to one line of source code? Definitely not. And what happens with a 'for' loop - part of its header gets run after each loop iteration but still kinda references stuff that was done once-only before the loop started.
