Doc: Describe property bindings in terms of relationships
- This patch aims to help readers think about bindings more
"declaratively" by introducing a new (albeit very leaky) level of
abstraction: Treat bindings as finitary relations, rather than mere
JavaScript expressions.
- In essence, property bindings are for describing relationships between
properties. The fact that the QML engine reactively updates a
property's value when its dependencies change, and the fact that
arbitrarily complex expressions are valid bindings, are simply
implementation details.
- Discourage the use of side effects in property bindings. They are not
essential for the main purpose of property bindings, they break the
finitary relation model, and their use can reduce code
readability/maintainability/toolability.
- Discourage complex property bindings for similar reasons.
