Ok so I'm using Github gists api from here.

I'm trying to get the filename and raw url of each gist, I'm halfway done, but hit an odd roadblock.

So far $gists[0]->{files} gives me the files portion of the gist. See the whole json structure here.

$gists[0]->{files} looks like this with Data::Dumper.: 

$VAR1 = {
          'main.html' => {
                           'language' => 'HTML',
                           'filename' => 'main.html',
                           'type' => 'text/html',
                           'size' => 713,
                           'raw_url' => 'THIS IS WHAT I WANT'
                         }
};

I get to the filename with this: 

foreach my $g (@gists) {
        my @files = keys(%{$g->{files}});    
    my $file = $files[0];
        # $file is now main.html

    print $g->{files}->{$file}->{raw_url};
        # ^^ THIS doesn't work!!!
}

It gives me this error:

Can't call method HASH(0x7f81c547aea8)'; without a package or object reference

So what am I doing wrong? Is it because there is a dot in the hashname? I've seen examples of strings being used as a hash key
