sure, since you use a \def which then stores catcodes as they are in tex
mode

\startluacode
       function document.luigishouldknowbetter(whatever)
               for i=1,100 do
                       print(whatever) -- this is a lua comment
               end
       end
\stopluacode

\def\Foo
  {\ctxlua{document.luigishouldknowbetter("Hello world!")}}
