[VPM] programmically create keys and vals for anonhash

[Abram Hindle]

Hash: SHA1

You can convert an array or list to hash just by assigning it:

%hash = qw( key1 value1 key2 value2 key3 value3);

Hashes can be formed from lists and array of an even number of elements
where keys and values alternate.

	$hash{$1} = $2; #works

	push @headers,$1,$2; #works
	...
	%hash = @headers;
