Die::Retry - a perl module to easily retry on exceptions

I've just written Die::Retry - a perl module which makes is easy to write a concise exception retry loop.

The module is only useful if any exception can be silently caught and the code in question re-run, but in that case it makes it very easy to write the loop in question:

1    use Die::Retry qw( retry );
2    my $retval = retry( sub { some_func_with_exceptions($param1, $param2) }
3                            , times => 3
4                            , delay => 0
5                            );

In that example the code ref:

1  sub { some_func_with_exceptions($param1, $param2) }</pre>

is called up to three times if exceptions are thrown. There is no delay between retries. Finally - if a successful call is made to the code ref $retval will get the (scalar context) return value of the code ref call.

I'm submitting this to CPAN and have already set it up on GitHub and Ohloh.

I've just found Attempt which does exactly what I coded for Die::Retry - in fact both the code and the syntax are practically identical. So dies Die::Retry.

Blur "The Best Of" Album Cover - Turkish Rail style

While travelling through Istanbul on the train I happened to notice that their 'make this seat avaialble to folk in need' sticker held a certain resemblance to a Blur album cover:

Blur The Best Of Album Cover Turkish Rail sticker merged with Blur Album

Albeit without the "blur" label! :)
