Sorry to heat up this stale topic, but I've just been bitten by this:

#!/usr/bin/perl

use Modern::Perl '2015';
use Try::Tiny;

sub foo {
    try {
        say 'foo try';
        die;
        return 'try';
    }
    catch {
        say 'foo catch';
        return 'catch';
    };
    say 'foo outer';
    return 'outer'; 
}

sub bar {
    eval {
        say 'bar try';
        die;
        return 'try';
    } or do {
        say 'bar catch';
        return 'catch';
    };
    say 'fos outer';
    return 'outer'; 

}

say 'begin';
my $r = foo();
say $r;
say "########";
my $s = bar();
say $s;
say 'end';

So there is a subtle difference between eval ... or do and Try::Tiny: in the latter, return doesn't mean what you think it means even in the catch block.

In hindsight, it's obvious, and it is even documented explicitly, still, this behavior makes Try::Tiny slightly more inconvenient.
