underscore.lua's Issues

function compose bug

When we use underscore like this:
us=require "underscore"
f=us.compose(print,function(a) return a+1 end)
f(1) will trigger this bug.

Maybe in line 359
"return funcs[1](call_funcs%28_.rest%28funcs%29, ...%29)"
should change as
"return funcs1"

_.reduceRight equivalent for Lua

Hi, I am trying to port an existing JS framework to Lua, the framework uses underscore.js in most parts, I stumbled upon _.reduceRight but it's implementation is not found at http://mirven.github.com/underscore.lua

Wrong example for _.include

http://mirven.github.io/underscore.lua/

The example does not work:

_.include({1,2,3,4}, function(i) return i%2 == 0 end)
=> true
_.include({1,3,5}, function(i) return i%2 == 0 end)
=> false

The most annoying "feature" in underscore.lua

I would expect all to treat nil as false as with anything else in lua.
However, this is not the case.

> return underscore.all({1,2,3, false})
false
> return underscore.all({1,2,3, nil})
true

While we all know that in lua

> if nil then print "a" else print "nil is like false in lua" end
nil is like false in lua

table size

Add function _.size(table) to determine number of elements in an arbitrary table (so it will work like #_.keys(table))

Typ in chaining docs

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

missing clone from underscore.js

sad face
