in reply to Try::Tiny catch block with $_ eq ''

What I prefer to use is Exception::Class, in conjunction with Try::Tiny.   You can die (that is, “throw an error”) with an object as well as with a string, and this gives you a well-defined way to communicate between the point of the error and its ultimate handler.   (Wrap “legacy code” sections in a handler that catches the (string ...) exceptions and throws an object containing, among other things, that string.)

An exception class can not only carry any sort of a “payload” (including undef values as-needed), but it is also self-identifying you have not only the class-name but the entire class hierarchy that you’ve cooked up.

[perldigious]: Also coincidentally, I'm currently in the middle of a winter storm that has dropped 1 foot of snow and is expected to drop another. I might have to adapt this for customers/vendors who come visit and put it at the beggining of every presentation I give.
[Discipulus]: the photo was removed... Cyrano de Berjerac was not of the same idea..
[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"
