[kamloops-pm] Hello

[Bradley K. Embree]

	use strict;
	use warnings;

	my %hash = ( foo => 'foo',
             	 bar => 'bar',
             	 zed => 'zed'
           	     );

	my $foo = 'bar';
	sub foo { return 'zed' }

	print $hash{ foo   }, "\n";
	print $hash{ $foo  }, "\n";
	print $hash{ &foo  }, "\n"; # or $hash{ foo() } or $hash{ &foo() }


Perl does make it very easy to write confusing code.  ;)
