What scenario are you envisioning that a print failing will be the sole indicator of a failure state?

You can have a print fail due to, for example, lack of space on the device and then have the close succeed later on.

There's also the argument that it's better to FailFast.

    If you're printing to a filehandle, then use a IO::File-derived class that will encapsulate that die for you, and test that. I'm not quite sure how STDOUT or STDERR runs out of space, though.

    • In general, if you think something isn't in Perl, try it out, because it usually is. :-)

[Corion]: Meh. I think I have now the parts down that I want from a simple Javascript frontend for single-page- applications with a aPerl backend. But it seems that all Javascript templating modules either don't support two-way binding (which would be nice) or ...
[Corion]: ... don't support server-side precompilation (which means the client has to compile all templates to Javascript themselves), or are giant frameworks that expect to do everything (which is not what I want)
[Corion]: I feel that there is a talk somewhere in there, either about the structure and parts, or how I used several parts to get a complete whole.
[Corion]: Maybe I can still find something that is compatible with handlebars.js (which has JS precompilation) but allows for two-way data binding (which is great for the UI)
