in thread Can someone please write a *working* JSON module
Q4) What operator is this? I believe it takes my global value of 1 for $debug and makes it zero
It is the defined-or-equals operator. It assigns the RHS to the LHS only if the LHS is undefined. It is listed in perlop along with all the other operators.
