I always do things like this:

my $ok = eval { do_something(); 1 };

if (! $ok){
    handle_exception(); # possibly use contents of $@
}

If I'm only doing one thing in the if block, I often will write it more compactly:

handle_exception() if ! $ok;

Sometimes I just want to croak with a separate message instead of the one generated by (perhaps not even) my code:

croak "damned module failed with a confusing error\n" if ! $ok;

[download]

These types of things are found all over my test suites. Here's one example from one of my CPAN distributions.

What this does, is if the function/method called inside the eval dies/croaks, eval returns undef. If it succeeds, it returns 1/true.
