Methods in OCaml which don't take any parameters don't require the dummy unit arg, ie writing:
method foo = ...
is fine. The reason you might need the unit arg is if you need to create a closure from the method without calling it, for example if you need to use the method in a callback.
In lablgtk2 the convention is to use unitless methods if either: the method shouldn't be used as a callback; or: (conceptually) the method doesn't change the object's internal state. Let's do that here. ---
Ah OK, it makes sense. I chose the safe way and added the unit arg to avoid issues with closures, although I'm fine with the change given that it follows an established convention. Thanks, -- Pino Toscano
