Just wondering, is keys() optimized for void context?  Perlfunc only states:

   As a side effect, calling keys() resets the HASH⤁s internal iterator...

If it is _not_ optimized for void context, I think it's "easy" to
reset rather than "cheap"  ;-)
If keys() _is_ optimized for void context, a change in the
perlfunc.pod seems to be in order.
