[LA.pm] Usage of =>

[John Beppu]

Hey Robin,

=> is a glorified comma that quotes the bareword that precedes it. 
Therefore ('key', 'value') is equivalent to (key => 'value').  If you
want to write a sub that can accept named parameters, you'd usually do
something like this:

sub foo {
  my %param = @_
  print "x is $param{x}; y is $param{y}\n";
}

foo(x => 8, y => 16);
