What aspect of rules makes Gosu rules suitable for complex logic?

Gosu rules are particularly suitable for implementing complex logic due to their foundation in a flexible programming language. The flexibility of Gosu allows analysts and developers to express intricate conditions, operations, and workflows that are common in insurance processes. This capability is essential for capturing all the nuances and details that complex business rules often require.

Additionally, since Gosu is a statically typed language with advanced features such as closures, generics, and a rich set of built-in libraries, it makes it possible to manage complex logic efficiently. As a result, users can create sophisticated rules that may involve conditional logic, looping constructs, and object manipulation, which would be difficult or impractical to achieve with rules that are limited to simpler structures.

The other aspects mentioned—limitations to simpler logics, non-developer creation, and maintenance in the Business rules AI screens—do not contribute to the handling of complex logic in the same manner and therefore do not support why Gosu rules excel in this area. The versatility and power of the Gosu programming language itself are what specifically enable the development of complex business rules within the Guidewire environment.
