I'm trying to index into some function parameters that
are passed as array references.
Is strategy #1 (see below) identical to strategy #2? I
thought so. I had a bug I that I fixed by recoding
strategy #1 as strategy #2 and it fixed the problem.
This leads me to believe they are not identical. What
is the difference?
Thanks,
Siegfried
sub f {
my ($y) = @_;
# strategy #1
print $$y[0];
# strategy #2
print $y->[0];
}
my @x = (1,3,3,45);
