* Here is an example of a complex expression:

* NULL, "item");
* expression = gtk_property_expression_new (GTK_TYPE_COLOR,

* NULL, "item");
* expression = gtk_property_expression_new (GTK_TYPE_COLOR,
* color_expr, "name");
* ]|
*
* when evaluated with `this` being a GtkListItem, it will obtain the
* "item" property from the GtkListItem, and then obtain the "name" property
* from the resulting object (which is assumed to be of type GTK_TYPE_COLOR).
*
* A more concise way to describe this would be
* |[
* this->item->name
* this->item->name
* ]|
*
* The most likely place where you will encounter expressions is in the context
* of list models and list widgets using them. For example, #GtkDropDown is
* evaluating a GtkExpression to obtain strings from the items in its model
* that it can then use to match against the contents of its search entry.
* #GtkStringFilter is using a GtkExpression for a similar reason.
* #GtkStringFilter is using a GtkExpression for similar reasons.

* By default, expressions are not paying attention to changes and evaluation is
* just a snapshot of the current state at a given time. To get informed about
