Set $@ within catch {}

[FGasper]

The fact of using $_ rather than $@ within catch {} blocks has a couple of unfortunate effects:

1. You lose access to $_ from outside the try/catch. This has never really bothered me, but I could see it bugging someone who uses $_ in iterations more than I do.

2. Setting $@ is the only way to get PROPAGATE from Perl exceptions. The fact that T::T uses a different variable makes anyone who wants PROPAGATE to do local $@ = $_; within every catch {} where we might potentially rethrow the exception. This is annoying.

I propose a flag, and/or some other means, of telling Try::Tiny to set a local()ized $@ as the exception variable within catch {} blocks.

Thoughts?

surely propagating the exception is as easy as die $_; ?

@karenetheridge No, because that doesn’t fire PROPAGATE.
