I take it you mean it should only happen when you write to a location
($c->[3] = 'foo') not when you read from a location (print $c->[3]) ?
I would think that $c->[0]{a} is an lvalue by most definitions - it's
a value which can be written to. It's an lvalue even when on the right
side of an assignment.
