so you are a step or two deeper to what i was thinking. thanks for clarifying. (sorry, i need to wrap this in my words to get a glimpse of it). second shot *peng*

mathematical proofs are written by few and read by many. lets assume that a script is also read by many. sure, the writer must expect a reader to be at a certain level of skill. otherwise immediate understanding will not be possible. the writer comments all stuff he thinks that can be misinterpreted, and stuff he knows is his usus (and perhaps more); so that if you read the script, it makes perfect sense.

but this seems to be the exception. with the effects of the personal belief system, everyone has an other view of the solution of a problem. so if the reader does not understand, he is either not qualified enough or he cannot see the intentions the writer had while writing it. in the latter case, there is an information loss; this information should actually be represented by a comment.

a perfect script is one that its writer has all his belief knots undone and everything he cannot expect a reader to know is either transported by a good naming scheme or by comments. that means, there are no perfect scripts because it is dependent on the knowledgelevel/belief system of the reader.
