The provided code is actually visually very helpful, as it leads (mind you, leads, not misleads) the reader to think that bar() makes sense in the context of foo().

Maybe that code documents that its author intended such a thing, but to an experienced Perl programmer, I suspect that the code instead reads as if the author doesn't know how lexicals and sub declarations work in Perl.

    [Discipulus]: everything is .* in regexes: it has drawbacks (can be nul, is greedy..) so /hey.*,0$/ can be a solution
    [Discipulus]: but pleas take a look here (page 97) and to standard documentation
    [Discipulus]: perlre and perlreref
