in reply to Capturing the nth word in a string

Your @{[$str =~ m/\w+/g]}[3] would be better written as ($str =~ m/\w+/g)[3]. I'd more likely write it as, my $nth = (split ' ', $str)[3]; though that's not exactly the same thing with respect to punctuation, etc. Whether that is as usable to you depends on your data.

    Yes you are right. ($str =~ m/\w+/g)[3] is better than @{[$str =~ m/\w+/g]}[3]. I came up with my original solution because I first wanted to do @{$str =~ m/\w+/g}->[3], but that was obviously wrong. So I wrapped it inside @{[ ... ]} to make it work.

    And yes I would use split normally, but that $m = $str =~ m/\w+/g idiom and davido's meditation on TMTOWTDI inspired me to come up with something similar.

      You wanted to say:
      [$str =~ m/\w+/g]->[3]
