A variation of chaining associativity gets used, with the "chaining rule" being '$v1 op1 $v2 // $v1 op2 $v3' instead of '$v1 op1 $v2 && $v2 op2 $v3', as is the case for comparison chaining.
But wouldn't that make: True ?? undef !! Moose; evaluate to Moose, instead of undef as we wanted? Cheers, Audrey
