in reply to Cheap idioms

I would write it in its own nice-named function, even if the function body contained the idiom.

Cute, and I note that the module File::Slurp doesn't do it that way!

I agree with tye. What if you were doing this in an older version of Perl and the problem was brought to your attention? You would have to find and fix every usage. But if using a module, fix it once. The module might grow and handle accomidations, nits, and other issues. Everyone benifits from that experience.

BTW, I recall not using File::Slurp somewhere, because, like yours, it doesn't do binmode.

[Corion]: ... transfers in the background. Now that I think about it, this maybe even means that I can run the OpenGL filters on Youtube input :)
[ambrus]: Corion: I mentioned that the unix event loop of Prima always wakes up at least once every 0.2 seconds. Have you found out whether the win32 event loop of Prima does that too?
[Corion]: ambrus: Hmm - I would assume that the onDestroy message is sent from the destructor and doesn't go through the messageloop, but maybe it is sent when a window gets destroyed but all components are still alive...
[ambrus]: Corion: partly deep source dive, partly just conservative coding even if it adds an overhead.
[Corion]: ambrus: Hmm - no, I haven't looked at wakeup intervals ... I wonder why it should want to wakeup periodically because it gets a lot of messages from the Windows message loop (on Windows obviously)
[ambrus]: (Alternately a deep source dive and then rewrite that event loop to make it better, and then as a bonus you get an idle method.)
[ambrus]: The 0.2 seconds wakeup is likely a workaround for some bug, but I can't guess what bug that is.
[ambrus]: It's been there since Prima 1.00 iirc
[Corion]: Hmmm... Weird. Maybe it needs that for doing its timers or something. Still weird.
