  • With perl, a coderef is a subroutine, basically.  With rubies coderefs, they are more like perl's blocks:

    use feature ':5.10';
    sub foo {
       say 'beginning of foo';
       bar();
       say 'ending of foo';
    }

    sub bar {
       say 'beginning of bar';
       my @foo = grep { return } (1,2,3,4); # I'd say this should mean none
       say 'ending of bar';
    }

    foo();

    Note that the grep kills bar.
