in thread Shortcut operator for $a->{'b'}=$b if $b;

overload doesn't define operators; it redefines them. ?= would have to be added to perl by patch.

There is an alternative to a new or overloaded operator. One could use a tied hash. The only difference would be in the setter.

By the way, my function does not autovivify. At least, not in 5.6.x or 5.8.x.
