Hi All,
  I've been reading through some Perl code. I've come across a bit that uses _ in a way I'm not familiar with and I can't find docs on it:- 
    my $filename = shift;
    return 'link'  if (-l $filename);
    return 'file'  if (-f _);
    return 'dir'   if (-d _);

I can see what is happening. But I don't know why? I don't understand why the _ doesn't have a sigil?

Would someone be kind enough to fill me in?


Lyle
