I mean don't write
do something;
but write
something();
since it is, in effect, a function call. Then go all the way and rather
than writing
something:
/* code for 'something' ... */
write
void something()
{
/* code for 'something' ... */
}
You are re-inventing local functions. Just go the whole hog and allow
local functions, because the function abstraction is familiar and yet
more flexible.
