I agree, and I think there is a use case for &&= as well. Suppose
that x is either an integer or null. Then
x &&= x + 5;
will increment x by 5 unless it is null, in which case it will be
left alone. (This will not work in languages where 0 is false,
like C and Perl.)
Clear? Huh! Why a four-year-old child John Cowan
could understand this report. Run out cowan at ccil.org
and find me a four-year-old child. I http://www.ccil.org/~cowan
can't make head or tail out of it.
