Why is it a problem? It should be obvious to an user that a property=20
could have an initialization value with a default setting. If you are=20
in the IO monad it should be clear enough that the second form first=20
creates the widget using default settings and then sets the properties;=20
the only alternative I see would be an (infamous) GUI monad which=20
people seem to dislike: even if you could hide the widget and show it=20
on demand, there might be other things unrelated to graphics that=20
behave differently if done during initialization or after, do you=20
agree?
