The only reliable approach I know is to put everything in one
function, and program the calls explicitly using goto and use
labels-as-values for the unavoidable returns. The resulting program
should be decent enough performancewise, but the compiler may have
difficulties compiling the resulting huge function. Daniel Diaz'
wamcc system uses an approach like this.
