Detailed On-line Explanation of What's New in 5.1?

[Veli-Pekka Tätilä <vtatila@...>]

Hello again,
On to the second question:

Where can I get a long explanation of what's new in Lua 5.1? The modules 
sample chapter of PIL 2nd ed made that part clear, and I know the library 
changes and length from the reference manual, but howabout the rest of the 
features.
Most of my Googling has really brought up presentation slides, ref cards 
etc... which are a bit too compact reading to my taste, though helpful. I'm 
also not into tutorials much, preferring to read about the thing and try it 
out myself rather than read the code.  Since I'm legally blind, I'd need to 
buy an accessible e-book version of the PIL 2nd ed, or have it scanned and 
OCR:ed for the real long explanation, <smile>.
In particular, the new var-arg syntax baffles me even having read the vararg 
second class citizen article in the Lua wiki. Why the change to make vararg 
processing more cumbersome? I do liek the fact that the list has a name like 
... now, and you can even pass such lists to modules. Which reminds me, can 
I pass extra args to modules when requiring them, like i can in Perl's use 
operator? How does the module magiclly get its name as the first element of 
... anyway?
