What about something along these lines:
local function import( aName, ... )
local aModule = require( aName )
local aFunction = debug.getinfo( 2, 'f' ).func
local _, anEnvironement = debug.getupvalue( aFunction, 1 )
for anIndex = 1, select( '#', ... ) do
local aName = select( anIndex, ... )
anEnvironement[ aName ] = aModule[ aName ]
end
end
import( 'math', 'min', 'max' )
print( min )
print( max )
