Actually the braces are not mandatory if you use the method as a statement.

You can do:

MyTreeView.MoveNext

or

MyTreeView.MoveNext()

But you must do:

WHILE NOT MyTreeView.MoveNext()

The interpreter could deal with 'WHILE NOT MyTreeView.MoveNext', but I find it 
very confusing for the user: is MoveNext a property or a method ? 

I have an implicit rule in Gambas: a property is fast and light, while a 
method could be long and heavy. So the braces let the user see immediately in 
which case it is.

When using a method as a statement, it is not ambiguous, as a property cannot 
be a statement, except in an assignment.
