No need to force, just allow. For example let's say I have a case
statement like this:
case SomeVar of
 	1 -> do_something;
 	2 -> do_otherthing
end,

Then I realize that I need to handle the value of 3 also, so I just add
a line:
case SomeVar of
 	1 -> do_something();
 	2 -> do_other thing()
 	3 -> do_some_other_thing()
end,

and I get compilation error. Actually this is the most common
compilation error I receive. If erlang would allow syntax like this:
case SomeVar of
 	1 -> do_something;
 	2 -> do_otherthing;
end,

I wouldn't get these error messages. It's _really_ annoying.
