If you're interested in how to do dynamic loading in a clean
and elegant way, take a look at Inferno. Along the lines of
what you're suggesting, everything is a module. The only
thing necessary to make a module suitable as a program to
run from the command line is the existence of a function
called init() with a particular signature. After studying and
working with it, all of the other dynamic loading implementations
out there are... well the word that comes to mind is 'disgusting.'
