err... if all you guys are referring to the one who wrote
chocolate factory- it's Roald Dahl. 
Hi, Small boy, exact sentiment on the part of not compromising the
language. But still, being in the studies of linguistic and
communication myself, I do not reckon you heard of a phrase, a
method of "creative writing"? There are basically no fixed rules in
languages. Minority groups develop their own style of language, so
long as among themselves, it forms a form of communication.
If you are referring to writing for the masses, then of course,
target audience is one key element to consider.
if it's the grammar you are concern, then this is no place to
discuss, because, it has to go all the way back to primary school
studies.
So, basically, I am replying this message because I don't think
your argument / point of views are properly set out. Am interested
to hear your views. 
cheers all!
