When dealing with empty strings, I'd rather check length

Edit

  DB<13> p "false" unless "0"
false
  DB<14> p "false" unless 0
false
  DB<15> p "false" unless length "0"

  DB<16> p "false" unless length undef
false
  DB<17> use warnings; length undef

  DB<18> p "false" unless length ""
false
  DB<19>
