Yes, rolling your own is the style of the house:

local function Copy( aValue )
        if type( aValue ) == "table" then
                local aCopy = {}

                for aKey, aValue in pairs( aValue ) do
                        aCopy[ Copy( aKey ) ] = Copy( aValue )
                end

                aValue = aCopy
        end

        return aValue
end

But... as both Manel and Doug have pointed out, there are many 
resources for you to peruse for inspiration:

http://lua-users.org/wiki/StandardLibraries

http://sano.luaforge.net/

etc...

Lua is a bit like an, hmmm, "auberge espagnole"... you get mostly what 
you bring in... :P
