which also means that the module needn't actually get require()ed

Indeed a rather useful idiom I find myself using quiet often: instead
of importing everything upfront, only do so when needed.
For example:
function IndexLink( aPrefix )
local HTTPExtra = require( 'HTTPExtra' )
local HTTPService = require( 'HTTPService' )
local WikiIndexService = require( 'WikiIndexService' )
local aFirst, aSecond = ( aPrefix or '' ):match( '^(%w)(%w?)' )
local aService = WikiIndexService( aFirst, aSecond )
local aURL = HTTPService[ aService ]
return aURL.path
end
