Editing WoW:API select

{{wowlua}}
Used to traverse a list. This function is usually used to capture the arguments passed to an ellipsis (...). The official usage of this function is to return a list (retN) starting from index to the end of the list (list).
 local ret1, ret2, retN = select(index, list)

== Arguments ==
=== Parameters ===
:;index
:: Any non-zero number or the string "#".
:;list
:: Usually an ellipsis (...).

=== Returns ===
:;retN
:: The number of items in the list or every value starting from index to the end of the list.

== Examples ==
 -- Common usage.
 local num = select('#', ...) -- Returns the number of arguments in the ellipsis.
 local arg = select(i, ...) -- Returns the value at index '''i'''.

 -- Print all of the function's arguments (those passed to the ellipsis (...) only) to the default chat frame.
 local msg
 for i = 1, select('#', ...) do
     msg = select(i, ...)
     DEFAULT_CHAT_FRAME:AddMessage(msg)
 end

 local a, b, c = select(2, 'a', 'b', 'c')
 -- a = 'b'
 -- b = 'c'
 -- c = nil

=== Catenation ===
select can be used to catenate a vararg list into an array. This is useful for returning info from [[API_GetBinding | GetBinding]], which returns a vararg list of unknown size.

 function MyAddon_Catenate(...)
     local t,v
     t = {}
     for i = 1, select("#", ...) do
         v = select(i, ...)
         tinsert(t, v)
     end
     return t
 end

== Notes ==
* ''list'' can be value1, value2, value3, ... valueN; although, you will never see it used in that manner since you can just access value1 through valueN directly.
* It is not recommended that you use this method on a table as you would have to pass the table to [[API_unpack|unpack]]() for every call to select (once plus the number of consecutive numeric indexes). For tables, use [[API_pairs|pairs]]() or [[API_ipairs|ipairs]]().
* Indexes beyond the number of list items will return nil.
: <pre>select(6, 'see', 'dog', 'run') -- returns nil</pre>
* An index of 0 will produce an "index out or range" error.
* Negative values wrap to the end of the list.
: <pre>select(-1, 1, 2, 3, 4, 5) -- returns 5</pre>
* A decimal index will be rounded to the nearest integer (1.1 rounds to 1, 1.9 rounds to 2).
* Passing a function that returns a list as a parameter to another function will pass each return as a parameter to the function as if you were manually passing each variable to that function, so ''tinsert(tab, select(1, ...))'', will have unpredictable results.
