in thread Shortcut operator for $a->{'b'}=$b if $b;
Maybe someone can suggest how to define a '?=' operator
$a->{'b'} ?= $b;
assigns $b to $a->{'b'} if $b is defined, does not autovivify $a->{'b'} if $b not defined
is that possible? - I'm thinking of use overload but I dimly recall that there is a finite set of operators you can overload and ?= isnt one of them.
