I respect your opinion, but I think this is not a good idea because it
means that all scripts enumerated are immediately loaded into the Lua
heap as chunk functions even if they are not executed yet. That is
why the c_loader call should be deferred until the preload function is
actually called. (Renaming the c_loader function to something like
load_script makes this easier to see. "preload" is actually kind of
an unfortnuate name, now that I think of it.)
Of course if it is _desirable_ to have everything in the heap at
startup time instead, then the above is inverted. :-)
