( [id://3333]=superdoc: print w/replies, xml ) Need Help??

So I'm writing some code to perfect-shuffle two lists, and I want it to complain when it doesn't get lists of equal length. Which style is preferred?

# .. or warn is homomorphic to the .. or die idiom, and is # phrased like an assert. @foo == @bar or warn "perfect_shuffle: lists must have equal length\n"; # explicit if makes adding cleanup easier, and is phrased # like an error check. if(@foo != @bar) { warn "perfect_shuffle: lists must have equal length\n": }
Opinions?

Edit: s/scalar \@/\@/g;; thanks adrianh!

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
