Xavante / Compat-5.1: reloading a module?

[William Trenker <wtrenker@...>]

What is the "proper" way to reload a module on the fly?  I am running
Xavante and have a custom handler that uses a module.  I want to be
able to change the module's source code and have the changes re-loaded
automatically without stopping Xavante.

I've been doing this:

--- myXavanteHandler.lua ---
module("myXavanteHandler")
local function myHandler(req, res, param)
    package.loaded.myModule = nil
    require"myModule"
    res.content = myModule.html(req.built_url)
    return res
end
function makeHandler (params)
    return function (req, res)
        return myHandler(req, res, params[1])
    end
end
--- end code ---

--- myModule.lua ---
module("myModule")
function html(txt)
    return "txt = "..txt.."<br />"
end
--- end code ---

The net effect is that when I change the code in myModule.lua, it will
be reloaded the next time the handler is called.

But is setting package.loaded.x to nil the design-intended way to
trigger a reload?  Will this cause problems with package.preload?

Thanks,
Bill
