gtk-expression-bind() seems to be wrong #137
Description
https://developer.gnome.org/gtk4/stable/GtkExpression.html#gtk-expression-bind
proc `bind`*(self: Expression; target: gobject.Object; property: cstring;
this: gobject.Object = nil): ExpressionWatch =
fnew(result, gBoxedFreeGtkExpressionWatch)
result.impl = gtk_expression_bind(cast[ptr Expression00](self.impl), cast[ptr gobject.Object00](target.impl), property, if this.isNil: nil else: cast[ptr gobject.Object00](this.impl))
result.ignoreFinalizer = trueExpression is annotated with transfer full, so we have to avoid calling unref on it.
