Code

#!/usr/bin/perl 
 
use strict; 
use warnings; 
 
$_ = "fooFOObarBAR"; 
my $count = 0; 
$count ++ while $_ =~ /[a-z]/g; 
print "$count\n";

__END__

I love Perl; it's the only language where you can bless your thingy.

Perl documentation is available at perldoc.perl.org. The list of standard modules and pragmatics is available in perlmodlib.
