Re: Re: The fastest way of searching a certain element in an array

Hmm..., surely it is not the fastest. Here is it's code:

sub first (&@) {
  my $code = shift;

  foreach (@_) {
    return $_ if &{$code}();
  }

  undef;
}

You can see, it is similar to my for_block which was benchmarked.

ccn, Here is it's code: Well that depends. As I indicated in Getting Matching Items From An Array, List::Util falls back to pure perl (which has obvious inefficiencies) only if the XS version is unavailable. Which version of 'first' did you use in your benchmarks? Cheers - L~R	[reply]

I benchmarked 'first' with XS loaded. To make shure that XS was loaded I've inserted some alerting printouts in pure perl version of the 'first'.	[reply]
