Perhaps I misunderstand, but when I have that variable set to nil, the
POD imenu entries go away, which is what the docstring says.  Indeed,
which-function-mode uses the imenu index for determining which function
point is in.  I don't know how often which-function-mode calls the
indexing function, so make sure you have the variable set before
visiting the file.  Try again and let me know.

I do think it's better to say that the definitions begin earlier than
what cperl currently says (though it's not a "bug").  However, I think
indexing the POD entries by default is the better way for several

1. cperl-mode already does it that way.
2. perl-mode does it.
3. There is no "pod-mode".  For editing pod files, perl-/cperl-mode is
   the best Emacs has.  Moreover, many people _do_ write plain pod
   files, in which case the entries should get indexed.
