in reply to Perl Idioms Explained - my $string = do { local $/; <FILEHANDLE> };

I've ++ed this, but I wonder whether it isn't time to remove glob file handles from documentation and replace them with lexically bound file handles? Instead of:
open FILEHANDLE,'filename' or die "open of 'filename' failed: $!\n";
at least show the more modern idiom:
open my $handle,'<','filename' or die "open of 'filename' failed: $!\n +";
I realize the title is "Idioms explained", but you're also teaching people new idioms this way. So from a teaching point of view, I should at least mention that there is a new and better way of opening files since Perl 5.6.0 (if I'm not mistaken).

[stevieb]: perldigious: video near our hq in Montreal. Here in Calgary, it's -28c... we've only got 3" of snow so far, but there are several feet in the mountains already
[perldigious]: Snowshoeing time stevieb? I need to buy a pair so I can walk my German Shepherd properly through the country.
[stevieb]: yeah, I snowshoe a fair amount in the mountains. I also use spikes similar to these very often as well
[perldigious]: Discipulus: alternate link
[stevieb]: LOL you can easily replace "Helsinki" with "Alberta"
[perldigious]: I used to live at the top of a very steep hill stevieb, I can relate to the video. Literally used to have to build up momentum and try to force my vehicle to make it up the hill to park in my driveway properly... didn't always make it.
[choroba]: Why don't they use tire chains?
