Actually, $g::TaskList is not used, named, or referred to in the entire module that the above code appears in (though it is global). (It is used by an upstream sub that calls down into this subroutine though, but wouldn't $_ at least be local to the subroutine?) Even if $_ somehow became an alias to a global variable that was not used in the module in question, how would using $_ as an r-value undef said global?

$Body .= $_;

How does that undef $_, or anything it might be aliasing to? Sorry if I'm not getting it (I understand the idea that making it local will fix it, but I'd like to understand what makes this not work in the first place, because I just cannot figure out how $_ became an alias to TaskList). Thanks for the continued attention. :)
