You noted some very good books and, yes, if we are talking shell programming they might be better places to look at compared to the Stevens. On the other hand - and this was my implicit point - I think there is something about how "good" programs are written which is absolutely independent of the programming language employed. Regardless of writing in assembler or the most high-level programming language there are some practices, some dos and don'ts which should be known by everybody before s/he even attempts "hello world". This is what Stevens talks about.

It might be easier to first read Eric Raymonds TAOUP, but - without wanting to take away from Erics achievement - at its very essence IMHO it rehashes what W. R. Stevens already laid down in his book. This is because the principles, the "rules" of our art are eternal and cast in stone.

Hash::Case::Upper(3pm)					User Contributed Perl Documentation				    Hash::Case::Upper(3pm)

NAME

       Hash::Case::Upper - native hash with enforced lower cased keys

INHERITANCE

	Hash::Case::Upper
	  is a Hash::Case
	  is a Tie::StdHash

SYNOPSIS

	use Hash::Case::Upper;
	tie my(%uchash), 'Hash::Case::Upper';
	$uchash{StraNGeKeY} = 3;
	print keys %uchash;  # STRANGEKEY

DESCRIPTION

       Hash::Case::Upper extends Hash::Case, which lets you play various trics with hash keys. In this implementation, the fake hash is case
       insensitive and the keys stored in upper-case.

METHODS

   Constructors
       $obj->addHashData(HASH)
	   See "Constructors" in Hash::Case

       $obj->addPairs(PAIRS)
	   See "Constructors" in Hash::Case

       $obj->setHash(HASH)
	   See "Constructors" in Hash::Case

       tie(HASH, 'Hash::Case::Upper', [VALUES,] OPTIONS)
	   Define HASH to have only upper cased keys.  The hash is initialized with the VALUES, specified as ref-array or ref-hash.  Currently,
	   there are no OPTIONS defined.
