Re^2: number array with space

Or a more Perlish way of using indexes (works only in a fairly recent version of Perl):

use Modern::Perl;

my @array = qw/een twee drie vier vijf zes zeven/;

for my $index (keys @array) {
    say "$index: $array[$index]";
}

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James

See Scalar::Util, and its function "`looks_like_number`". The module is core, meaning it ships with Perl. Dave	[reply] [d/l]

See looks_like_number in Scalar::Util like thus: `use Scalar::Util qw(looks_like_number); for(qw(1 perl 25 monks)){ looks_like_number $_ ? print $_," is a Number",$/ : print $_," is not a Number",$/; }` [download] Update: Awooooshhhh! davido, beat me to it.....
