in thread Beware List::MoreUtils natatime()!

Your bug sounds like your version is depending on an accident of not-quite recent perls. It used to often "just work" to say Carp::croak '...';. That was accidental and whenever you see an exception like this, just make sure to load Carp in advance of loading the thing you're using.

In your example, do:

$ LIST_MOREUTILS_PP=1 perl -MCarp foo

    Looking into the source of List::MoreUtils, I find:
    require Carp; Carp::croak "some message";
    That only works if Carp was already loaded. In older versions of Perl, there was a common pragma (vars?) that loaded it, but that no longer is loaded in 5.10.

    Hence the error. And another reason to not use List::MoreUtils.

      This fix is so trivial, it's not a real reason to avoid it.

        The natatime function is so trivial to write, there being a trivial fix is not a real reason to use a broken module.
