Re: question about data structures - what does $# mean?

So to get the number of elements in the array I try:

Wrong operator. If you want the number of elements in an array then just
use the array in scalar context, if nothing else then by using scalar().
$# OTOH will return the last index in that array, which is one less than
the number of elements unless someone messed around with $[.
But that does not work. It gives me 0.
Just as it should.
Meanwhile, this does work:
scalar(@{$d->{sid}})
Surprise, surprise.
