Re: selective join

Hi monks, I have an array like this:

Are you really sure you have an array? It looks to me like what you have is a hash disguised as an array. That is,

  my %record = (
      Currency => 'USD',
      Asset => 'Equity',
      Country => 'USA'
  );

If that's the case, and if the key structure is similar across multiple such records, your code would be significantly clearer if you write something like

  my $desc = join '_', @record{qw(Current Asset Country)};
[download]

(This assumes that your readers understand hash slices.)

<movie_critic_mode> Insightful! Beautiful! "I grinned broadly" </movie_critic_mode> No, really, now that you point it out, it may _be_ a flattened hash AM's playing with. And you point out a solution using hash slices because: using `keys %record` would be wrong as you can't guarantee the order that the keys will be returned. there may be other hash keys that he doesn't want to use	[reply]
