Recently, I believe we decided that {} should, as a special case, be
an empty hash rather than a do-nothing code, because that's more
common.
However, what do we do about:
while $x-- && some_condition($x) {}
Here, while is being passed a hash, not a do-nothing code. Should we
force people to write:
while $x-- && some_condition($x) {;}
Or should we make a counter-special case of some sort? Or should we
take out the {} special case altogether and force people to write
hash()?
