The elegance of computer languages ?

Why do I like Ruby ? 3.times { print "X " }
1.upto(5) { |i| print i, " " }
99.downto(95) { |i| print i, " " }
50.step(80, 5) { |i| print i, " " } Why do I like Java ? log.by('david').level(WARN).target('MyApp').send('localhost'); Why do I like Perl ? my %kv = map { $_ =~ /(\w+)\s*=\s*(\w+)/; $1,$2 } grep { ! /^#/ } <FILE>;
