This approach may work for you is the compressed data is actually
in a scalar and not too large. And not too small. YMMV.
my $z = read_file "product.json.gz";
my $io = IO::Scalar->new( \$z );
$io->seek( -4, 2 );
$io->read( my $buf, 4);
my $uncompressed_size = unpack( 'V', $buf );
This indeed does work in my tests. Thanks for all the help, Neil.
I really appreciate the time you spent on this.
No prob. Part of my thing on list reponses is that there is a seed for
others to learn from what was discussed.
I do wonder if there is a sane way to test for an in memory file handle
and give a more appropriate warning, but that is for further discussion.
