Typ in chaining docs

[veged]

http://mirven.github.com/underscore.lua/#chain contains _.({1,2,3,4}):chain() that's produce error '<name>' expected near '(' in my Lua 5.1.2
But _({1,2,3,4}):chain() (remove dot) work fine

I think it was mistake in docs.
First construction is invalid, because you need to point the method name after dot.
Correct the docs, please.

By the way, there are some incompatibilities with underscore.js.
For example "each" and "map" and many others methods in _.js pass three args in iterator functions (value, key, and list) but _.lua only value.
Also "each" have to work with non-number keys table.
