... and the easy way to remember the reason it parses this way is to recall
that O'Caml is a *function*al language, so *function* application binds
most tightly. :)  So in ``area#misc#realize (); area#mist#window'', the
application of ``area#misc#realize'' -- and not the `;' --  gets the ().
It's the same as with things like ``f x + g 3'' (= ``(f x) + (g 3)'', not
``f (x + g) 3'', or any other weird thing like that).

Hope this helps.

cheers,
William
