What about the implicit localizations of $_ done by map, grep, for, etc.? Do they do The Right Thing®?

I think it is surprising (hence bad) that the while ( <FH> ) idiom doesn't do an implicit localization of $_ like the looping constructs listed above. Is there a fundamental reason for this, or is it due to a severe tuit shortage?
