The Utility of In-Depth Tutorial?
but, i wonder the utility. For the 0.1% who need to know, you probably shouldn't (because you are probably abusing the language). And for the rest, testing code out yourself is more practical and reliable than book.
when you need to know some painful detail of a lang not covered by basic tutorial, you are on the verge of abusing the lang. Question your need/approach.
well, in depth tutorial is actually still useful, because the spec may be hard to read or doesn't exist. And, for many things, it may be hard to test to find out.
