  ~$ perl -e 'my $x = undef; printf "%d\n", $x'
  0
  ~$ perl -e 'my $x = undef; print "$x\n"'


The %d format numifies undef.

  ~$ perl -Mwarnings -e 'my $x = undef; printf "%d\n", $x'
  Use of uninitialized value $x in printf at -e line 1.
  0
  ~$ perl -Mwarnings -e 'my $x = undef; print "$x\n"'
  Use of uninitialized value $x in concatenation (.) or string at -e line 1.
